apr stage 3 slow?

[mrbogangles]

i bought the fueling here

put in the rs4 injectors, rs4 maf w/rs4 bosch sensor, rs4 accordian, i modified s4 airbox to fit rs4 maf, s3 apr ecu

i was expecting it to have a lot more humph
it spiked to 20 psi but tapered to 15psi is that right?
did the old v3 do that
the ecu has 4 slots all of witch spiked to 20 and stayed at 15 wtf is that
slot 1 seemed to be really slow in pick up too

compared to what i had before i felt no power gains at all
was running
rs4ko4
ghl dp
milltek catback
apr abox 93,stock,valet, 100
forge dv
stock fueling

[washyourrhands]

that really doesnt seem right to me at all

any stage 3 shouldnt feel slow

[AMC]

stock ic's? could be heat soak and or boost leak
log

[speedydragon]

vag com and log your times.

[mrbogangles]

yeah thats what i thought to
but it felt the same i didnt feel any power gains from what i had before
really disappointed

[Rated S]

APR can be considered slow compared to other Stage 3 OTS kits, but you should definitely feel a difference from Stage 3-.

[mrbogangles]

i have ipp ic in right know

[sti4now]

mine feels the same exact way. I have Apr k04 kit, apr fueling, apr chip and sometimes it feels strong as hell at spiking 25psi holding 22psi, but as of late I only spike 24 tapering to 16psi? some days its fine other its not I dont get it. Forge DV's stuck?

[mholme]

Yeah, something is definitely not right. I would do some logging and a pressure test. On a side note, it makes me glad I spent less and walk stage 3 S4's.

[mrpeterparker]

and what's your setup there ?

[fixn2xlr8]

Something is wrong at any rate, Im holding 20ish psi.

[Audone]

I hold about 21psi.. mind you im at nearly 4000ft above and have a few lemmitweaks..

The 91 program does feel slow after 93 and even more so after 104.. If I were you I would try and find out what isw in what slot.. it wont work in your avor to run the 104 program on 91.... Hell you could be on the stock program!
On my 93 program I cleanly walked away from a 3-.. there is no excuse to not feel faster.

But I agree with others.. Pressure test and go from there.

[mholme]

and what's your setup there ?

APR stage 2+ But I was completely joking..

ill do the pressure and logging
thing is i dont have a pressure tester and no vag com cable
do autozone have these items for rent

[2ndEngineS4]

Check list:

1. Pressure test (fix any boost leaks)
2. Log (replace any faulty parts)
3. Get better IC's
4. Realize that APR offers one of the most conservative stage III tunes (albeit very reliable)
5. Switch to another tune (if you want to go faster)
6. Watch your parts start to break.

Good luck.

no and no

You can easily make your own pressure tester tho

Build a pressure tester from Home Depot parts. It's on AWE's website with part numbers. You're gonna have to pick up some cheap air supply too if you don't already have it.

Someone in N.C. has a vag-com you can borrow. Post up in your regional forum.

my car is there right now and its the same setup as you.
your boost shouldnt drop below 20psi on apr's software. u need to pressure test it

what version of the apr file do you have ? your spikes and tapers are not right, I wouold assume that its still pretty warmm in az, so your spikes should be higher but more importantly, you should be holding 20lbs and not tapering to 15... whats up with the s3 ecu and not a s4 ecu ?? just for comparison my car holds 20-21 lbs in the 93 file

[md s4]

WOW, I was gonna say that that was a bold statement that you " walk stage 3 s4's " but then i see that you were kidding..

[CONTROL ONE]

I can't believe someone would even consider going to Stg III w/o a simple Vag-Com cable or pressure tester.

Those should be mandatory even at Stg I or less.
