APR stage 1+ @ 24 PSI?????

[dextrek]

Recently, temperature in Detroit has been dipping down anywhere between 10 degrees F to 0 degrees F. And I notice that my boost is hitting between 22 PSI to 24 PSI when WOT. I just thought it was boosting more due to really cold conditions and my ecu was adjusting to the cold weather, but the other night my CEL came on while boosting around 24 PSI. I restart the car and it was boosting normal but the CEL stayed on. So I got worried and stopped boosting hard...just in case. Any inputs why this is happening or anybody experience this with stage 1+? Also, can I damage my internals if I boost that high with K03?

[dirtybrd]

No, but check out that CEL.

[Papachristou]

i doubt you can hurt your internals on 1+ lol... mine regularly hits 23psi.. but it doesnt hold it, it just peaks... CEL is probably not related.. vag it and see

[festerfm]

when i got my 1+ i put the gauge in afterwards and got nervous as hell since it would spike at like 26psi for a split second but then back down to 21-22.... never had a cel tho.. it's not abnormal for me to see 22-23psi now.. i just enjoy it for the brief moment that it holds.. :-D

[Sablea4]

mine boosts to 25 sometimes. it could be the gauge. but 50k miles from me with no problems related to boost or internals. hope that helps

[vinny.dtw]

What gauges are all of you using...Could be the gauge being rather innaccurate like my stupid AWE one it seems.

[gotboost]

The most mine ever spikes to is 21psi

[absolutegtr]

I wouldnt be surprised if the code you threw was a lean code.

But what do I know....check that CEL

[a4wd]

misfire?

[chadb2434]

My GIAC 1+ usually spikes right at 21 and holds 20 or 19...

I think it might be your gauge...or mine

[BNZ TOY]

mine still spikes 17 and holds 15, i suck.

RPI says 14.5 to 15.5 is the norm for APR 1+, I dunno....

[a4wd]

^^ you should get that re checked... I get 24psi peak as well on my Revo 1+

[Sablea4]

im running a blitz digital turbo timer boost gauge combo.

[kwik_shift]

Autometer gauge hits 22psi and holds 19-20psi

[dextrek]

The weather got little warmer nowadays so I went WOT in 5th gear, and the car goes into limp mod, but I don't get a CEL. This happens almost evertime so I just use my APR code delete to get back to normal.

So I checked the CEL and it came out as P0234: Boost Pressure Regulation: Limit Exceeded (Overboost Condition). So I did some research on this and found that there could be several reasons for this.

1. Hoses incorrect connected, disconnected, blocked or leaking.
2. Malfunction N75
3. PCV Valve
4. Fuel rail pressure
5. Turbo itself...it is probably a stuck actuator on the turbo. Or the vaines inside the turbo are clogged up.

I am going to check for the leaks, the N75, and the PCV, but I am sorta worried that it might be my turbo. It's stock so it's not a huge deal, but I was planning on selling the car. Either way, any input will be appreciated. TIA.

[whiteUSPflow]

whats up with the APR code delete? is that what they call V-tune?

[dextrek]

No, I think they call it Fault Code Erase. It's just a way to get rid of CEL.

[coowhip]

sorry to thread jack, but should new CP's and plugs be put in before or after the reflash to 1+ on APR.

[lookaught]

Holding 21-22psi on a Stage 1+??? I didn't know it was that high. What rpm range are you seeing this pressure, and when does it fall off?

check your coils.

It hits 22 to 24psi around 3800 rpm till 4300.

How do I check if the Coilpack is bad or not? Any way to tell they are bad?

[vinny.dtw]

^ call me 810 three three three seven three three three and I'll walk you through replacing the coils. Its easy as PIE. Doubt anything is wrong tho if u can still drive with 20 psi plus.

How are you stage 1+ guys running 20+ psi boost? I peak at 15 psi with stage 1. Do injectors make that big a difference?

[chadb2434]

yessir!

[a4wd]

going from 1 to 1+ is a pretty big improvement.

FYI, changing my coilpacks, plugs, fixing the coolant leak and the boost leak makes me love my car all over again

[kwimberly]

Just got my injectors and 1+ reflash today - it definitely makes a difference! Right now I'm holding at 18-19! We'll see how it stays after a few days of the ECU adapting...

[jursch2211]

sorry to thread jack, but should new CP's and plugs be put in before or after the reflash to 1+ on APR.

I don't think its necessary but when I was having it done, I put new coils and spark plugs in before the flash.

[festerfm]

of course the injectors make that big of a difference.... they wouldnt be expensive if they didnt give a big improvement

[vinny.dtw]

^^did you ever race that gti or vr6...?

[GermanAudi]

of course the injectors make that big of a difference.... they wouldnt be expensive if they didnt give a big improvement

But how do bigger injectors give you more boost?

[old guy]

But how do bigger injectors give you more boost?

The injectors don't. The software tuning that goes with the bigger injectors changes the boost.

[festerfm]

But how do bigger injectors give you more boost?

your bigger injectors will flow more fuel than u'r stock injecectors in the same amount of time as your stock injectors. more boost requires more fuel. basically, your ecu knows how much fuel you need for a certain amount of boost, and all you have to do is tell your ecu what size injectors you have and it adjusts accordingly.

now that is straight from my pretend book called "turbos for dummies". in reality, it's much more complex, but that is the long and short of it..

[kwimberly]

of course the injectors make that big of a difference.... they wouldnt be expensive if they didnt give a big improvement

I don't know that I agree with the logic that if something is expensive it must give a big improvement, but since you dragged a freakin' deer out of the woods with your Audi I won't fight you on it!

[festerfm]

i swear to you that deer was huge... i got almost 60 lbs of ring sausage out of her and still got some burger, steaks, chops, and t-loin... she was huge... and in a nutshell, my previous post was a bit stretched. maybe i should ammend it and say when it comes to our audis, you can only have 2 of three things... the 3 things are easy, cheap, and effective.. if it's effective and cheap, it's not easy. if it's effective and easy, it's not cheap, and if it's easy and cheap, it's not effective.. and again, that only applies for 99.9% of things... there might be an exception.. i havent found it yet

[kwimberly]

^^^^

now THAT is an awesome formula. Applies to pretty much everything I've done to my car.

I am very interested in the APR stage 1+ set up. Has anyone run this for a long time to see how the engine holds up? Anyone here running the Stage 1+ alone without an exhaust or intercooler upgrade? I don't mind spending a few bucks on the TT injectors if it makes a big difference in performance without trashing the engine. But I don't want to then find out I need $2500 more mods to go along with it!

I ran Apr 1 for about 30k miles, and Apr 1+ for about 65k miles so total of 95k miles on Apr. No problems. I did have a aftermarket exhaust, but not a upgrade intercooler. You will get heat soaked, but thats ok.

[onlyaudis]

I guess without the exhaust upgrade, you will not get the top end power increases. How about torque at lower RPM's? Would the stock exhaust still do fine with stage 1+ in that area? I have got to hold the line on my mod budget somewhere. Plus, this is a street only car, and I really would like to avoid a louder exhaust. I already have a few classic sports cars if i am in the mood for noise! My old Abarth at high rpm's sounds like a formula 1 car.

[festerfm]

kinda tough for me to help here since i had the apr exhaust when i bought the car, but i'm a year and a half w/ apr.. had stage1 for 8 months and 1+ for 8 months more.. only thing i've had on for that time was the exhaust and a boost gauge. still holding up strong even at 116000 miles.

[LampyB]

i boost at 22-24psi with my Podi. the original podi i had boosted at 22psi, but once i swapped it out with the upgraded gauge it goes way higher, and the needle buzzes like crazy and fluctuates a lot too. sometimes when i turn the car off the gauge won't fully go back to zero, it'll stick at like -2inHG until i flick it. not the greatest...
