View Full Version : chipped K03 guys...how much boost?

I think Im having issues.

I saw 17psi spikes with my old VDO gauge, but have yet to see over 15 on my Podi. I love the gauge, but am worried it is not calibrated properly.

My problem goes beyond that though, there doesnt seem to be a spike. I will hit 14-15psi @4000 rpm but at 4500 it drops, no spike.

2 potential problems;
n75H, could be causing issues, but i seem to remember an increase in boost when i installed it, so im doubting it.

forge SPLTR, there are something like 50 points for spring adjustment, im having issues getting the right tension, part of me wants to ditch it.

i have a video i will upload later of only my boost gauge showing the lack of boost spike.

what are you chipped k03 guys boosting?

AEB, GIAC, n75H, 3"TP, stock exhaust>Remus muffler, K&N, Forge SPLTR

I spike around 18-20 I think and then drop off to about 15ish

I have a wett chip, scorpion exhaust, Forge, n75 race, silicon hoses... I think thats it.

could my exhaust be the restriction? i have seen quite a few guys hit 20psi, ive never been anywhere near.

30psi?

Subtract about 14.7PSI from that to get the actual PSI seen. You have to account for atmospheric pressure.

I spike to 17, can usually hold 15, it seems like it tapers off towards 10 way too soon though.....

if i could hit 20psi..... that would be the day.

my car doesnt spike either.. it just hits a value and holds there till 4500 ish and then tappers a few psi and holds that.

I hit 20 and taper to ~17-18

ST stage 1+ chip, stock cat/down pipe, 2.5 exhaust, intake and that's about it.

When I had a small boost leak on my 'L' hose off the intake manifold, I wasn't spiking. It just went up to 16psi and started dropping.

This is what the boost log looked like when I had the small leak:

Unfortunately I haven't compared the logs since I fixed the leak.

any more info on said hose?

i turned the forge up 5 notches and it seems to hold for longer, but its still not going above 15psi, i may try to turn it up more and see where that puts me.

i think when off my Podi reads about -1 instead of 0, but thats not a huge variance.

http://www.audizine.com/gallery/data/500/b5_l_hose.JPG

The location is roughly where it's shown in that picture. On the inside radius of the 'L', the stock hose cracks. It's a wimpy rubber material. When I got the new one from the dealer, it was an updated piece that had fiber strands, similar to a radiator type hose, and it was thicker.

I got lucky when searching for this leak. There's a lot of plumbing in our vac/pressure system to inspect.

Who knows if a vac leak is your problem though, but the symptoms your having were the same as mine when I had a leak.

02-27-2009, 05:11 PM
hmmmm.. .interesting.

well, guess our 'L' hose internet diagnosis doesn't apply!

The way I found that my L hose was bad was that the intake manifold was dirty right around where the tear was.

Have a look around if you see any dirt or marks on the surfaces adjacent to where hoses are. Also, inspect and bend the hoses to try and locate any cracks.

Could be a valve as well somewhere in the vac system.

Hope you find it, you should notice a little better perfomance once fixed!

I am spiking to 22 PSI then dropping hard to 10 PSI. LOL I need to get a better DV, i'm running stock!!

there is no way that your boost spiking at 22psi should drop to 10, it should hold at no less than 15psi at max......i spike to about 22psi and the holds at 18psi and it will only start droping from there after 5000 rpm, and still never drops to 10 psi.....you have a major boost leak....and if you say that you are still running a stock dv that should be changed, should never operate a stock dv on a chipped car, the diaphram is not made to take that amount of boost

the one you posted is a breather hose it won't affect your boost levels

thank you, i am now slightly less confused than i was 5 minutes ago, but overall more confused than i was before i started this thread. i cant believe no AEB guys have chimed in.

thanks all for the help so far, i will re inspect everything again tomorrow, the car is after all 12 years old, i assume most hoses are original

you have some serious issues there bud, i would say a boost leak but for suck slow spooling it would have to be a massive leak at that point it would not even make it to 15psi, K03's are very fast spooling turbos .....so i would have to say that your turbo might be on its last legs...

02-27-2009, 05:56 PM
are you guys talking about the slow build up from 11-15psi? because it jumps to 11 the second i step on the throttle.

again, i was cruising at aroung 3200rpm, and it dropped at 4500rpm.

are most k03 cars jumping to 15+ psi the second the throttle is depressed in 5th gear at 60mph?

02-27-2009, 06:01 PM

if you are in 5th gear at 3200rpm and you floor it you should go to full boost almost instantly.....at 3200rpm you will have full boost

AWM and I spike at 22psi. When I had a boost leak, it was at the L hose (breather hose) that was pictured being under the intake manifold (by the coolant tank). I went from spiking 22psi to ~15psi till it got fixed. You should do a boost leak test. That is the only real way to confrim if you have a leak and where it is coming from (besides visual/feeling inspection).

did you watch my vid on the first page? it jumped to 11 instantly and then tapered at 15 after a few seconds...i would think a turbo on its way out would be much slower.

i would think small boost leak, but i would have no idea where to look.

what are you chipped k03 guys boosting?

AEB, GIAC, n75H, 3"TP, stock exhaust>Remus muffler, K&N, Forge SPLTR

Unitronic Stage 1+(93oct) peak 18psi(slight hold), and holds 16psi for awhile but tapers to ~10-11psi at 6300+rpm.

GIAC 91octane tune should only be a 1Bar tune IIRC(14.5-15psi).


i cant believe no AEB guys have chimed in.

I has AEB yo!

02-27-2009, 06:37 PM

im greatful for some AEB input, these other boys boost crazy numbers.

.Mad Hatter.
02-27-2009, 06:43 PM
looks like unitronic only offers stage 1 for the AEB, so i assume its around the same as the GIAC tune; 195/215. if anything, GIAC claims more torque.

i feel better about this now, looks like maybe my VDO was slightly more accurate with 17psi (+2 with the n75h)?

AEB here - im not sure if we have this evil L hose that i have read about. the pics posted in the beginning were of different engine codes - post #22 etc - IIRC.
i think your boosting correctly - when i had the KO3 software from GIAC - i was boosting around 17psi, maybe a lil more higher gears.
there are still plenty of other areas we & everyone else can get leaks. if your still concerned about your boost, theres a couple of differnt types of boost tests you can do by pressiuze the system & listen for leaks.
in post # 32, that was the PCV breather hose i replaced when i pressurized my system. when i grabbed that hose with my had, it literally crumpled in my hand. i replaced it with that kit from ECStuning. the link below USED to have pics but i think there are still some PDFs on there that will help ..

Do you have an automatic? Because i'm pretty sure the ECU calls for incrementally higher boost levels as you go up in gears... only 5th sees full boost usually... that could explain the "step" of pressure in the video

its hard to see that main hose, you can kinda see if through the gaps between the runners on the intake manifold. if you unscrew the coolant tank (leave the hoses connected), you can flip the tank on its side & you can get a better view under the intake manifold..

*Waives B/S Flag*

I have Stage 1+. They just don't advertise anything higher on their website.
There's a LOT of tunes Unitronic (and other companies) hide away for special purposes.

AEB has Stg: 1, 1+, 2, and "3"/BT tunes. They don't advertise anything bigger than the 415/440cc files for the AEB because it's a narrowband O2 car.

They have files for 310, 380, 415, 440 and 630cc, and IIRC 550cc files.

It's kinda like going to a liquor store and asking for what they have in the back. You know they have some good stuff that they don't show everyone, it's there and waiting.

EDIT: Uni Stg 1 (91 oct) is 195hp/201tq
. . . . Uni Stg 1+ (93 oct) is 205hp/215tq
I hear stg 2 (93 oct + cat delete) is 220/230, but please don't quote me on that. I think it's a K04/310cc file though

oh ok, i was just going by the 034 site.

like i said, i know i hit 17 before with the GIAC tune and the n75H...its gotta be the gauge. keep in mind that it was calibrated at a drastically higher elevation, which may be an issue.

n75h is race right? yeah, then you have a 1 bar tune. race valve lets ya get 1-2 more psi.. and 1-2 less would put you at a 1 bar file..

idk, nic got his in the mail and got it installed.. it ran dead spot on as his VDO, right out the box.

you could ask winston on here and see if that could make a difference.. but places like stewart warner, autometer, they sell gauges to everyone anywhere and they dont custom calibrate for the elevation, but the car itself would pull more or less at elevation change, which would show on the gauge, but the gauge should work at any elevation, the same.

I would build a boost leak tester out of PVC, its a lot easier to use then the tennis ball method. Hard lines on those gauges get brittle from the hot and cold and crack pretty easy.. or you might of just wore a 'cant see' line out.

cant remember if you have done that yet or not.

have not done a leak test...i find it hard to believe that i got a leak at the same time that i got the new gauge.

and ya, n75h is the ecs valve thats branded as the race valve. i may pull the gauge out and make sure my line is not kinked...i was going to ask nic but wasnt sure if it was mounted yet. maybe a bad unit?

it could be a bad unit or a kinked line. did you use your VDO fitting or the fitting from podi?

could also be leaking where the hard meets the rubber inside the gauge holder.. pull the gauge out, unplug it and slide the vdo on, hold it and go for a certain gear pull and see if its the same as it was before or if the vdo reads low too.

vdo is long gone :(

the fitting (hard line) is different, completely different. the vac line is on snug though, i know that for sure...

heres my thinking out loud.

the fitting on the podi gauge sticks out more than the VDO, and the gauge itself is longer. there may be a kink right at the joining of the vac line and the fitting on the gauge, but i figured i would have noticed something like that.

ill check tomorrow and report back, if thats the case im going to feel like a tool.

oh so you reran line and all? nic reused his old line,etc. but put the podi fitting on the gauge.

def report back.

no i did the same. same line just new fitting and new gauge.

wow!

just spent the last couple hours reading and researching, mainly the forge valve. turns out that you are supposed to set it fully counter clockwise (softest setting) and then see if it rattles, if so increase tension slightly, if not then dont. essentially, you want it at the softest setting without loosing boost.

mine may be waaaaay too firm, which could be causing my odd 'slow' build up of boost...back out to road test again...ugh

edit: after some more closed course driving, ive learned alot about my splitter valve. i reset it to 0, all the way clockwise. from there 2 clicks holds 12psi, and 3 more making 5 clicks total holds 14psi. i was at something like 23 before, WAY too stiff. i will go 2 more to 7 and see how that fairs tomorrow.

... I definitely have too high pressure of a DV Spring in mine. It's been like that since I installed it, and I intended it to be like that.

i checked the line, think i found my problem. my gauge is mounted in my center vent. the vdo had an in line connector from the vac line to the gauge. the one in the podi is a 90* fitting, and it will only sit pointing to the right (pass. side). my vac line is run under the steering column, ergo, the line is kinking at the gauge because the fitting is pointing the opposite way that the line was run.

i need to try and get an in line fitting, then i SHOULD be good to go.

still trying to fine tune the splitter...might be easier when i can actually get a real psi reading, lol. i may trade it straight up for a 007

makes sense - you changed your gauge, and then you were getting funny readings.

I had some funny readings when I had a kink in my line as well.

i had a bad leak. fixed it with no mbc now peaking 17psi on speedtuning stage 2 (1.3bar) software

i fixed the kink and repositioned the fitting with the hose going the way it should be. it 'seems' to be better, but i have now tweeked my splitter valve, so until i actually fine tune that, i wont know if i am holding the proper boost, or if im losing it at the gauge.

im at 10 clicks so far, working my way up

Score..this thread just prooves im chipped then..
Put in the replacement ko3 2 weeks back and she spiked to 20 psi, maxed out my guage but then backed off down to 14 - 15

can i ask why?

i fixed the kinked line, and i adjusted the splitter to 25 clicks, seems to build and hold 15psi better than before, but it still wont pass 15.

wouldnt a stiffer spring prevent boost from peaking, or could i continue to increase tension until i lose boost?

And I like the response better. Obviously I'm not going to claim to be more intelligent than the people that engineered the piece, but I know what I like, and what I prefer. I just like it that way.
