Talking FP Green on 04 STI, tuned by Jr at The SHOP **NEW NUMBERS**

What do you guys think? We had a lot of problems and Jr didn't want to push it untill i get beter inj, get a stronger BOV, a front 02 sensor, and for some ****ing reason my Walbro pump started to act up so they want me to get a new one with a catch can. Here is were we are at right now, but can't really get on it b/c they said " It will blow up"

Well after spending much more money and time then i was planning we finally got what i wanted and it runs like a baby. Like i promised here is the NEW dyno sheet.

at 22-23PSI

This isn't the place! Yes those are all possibilities! But to question your tuner and his shop is a little overboard just because your upset and things didnt go smoothly.

Owww no no no, i am not questioning Jr at all, he is a great tunner, if not the best. The whole shop was grat last night and i am not bashing on him at all. I'm pissed at myself and myset up. Jr did his best and that is why i drove for 3hr. We had the car on the dyno for 4 hr and everybody stayed till 830pm trying to get me out of there, soo i have nothign but great words about Jr and The Shop. They gave me a shopping list of what i need, and after i get all of that i'm going back there.

Did you do the work to your own car? If you do make sure you double check everything twice. clamps fuel pressure all that good stuff. Make sure there's no oil on your intercooler pipes where the couplers clamp down that's how things leak and pop off Make sure that surface is clean and dry.

That's the best word's I can give you. Jr's cool people. And a great tuner...

at first we only had 300whp but after finding some hoses popping off and some clamps loss we got it to 360. The BOV is only rated to 18psi so that was one of the prob, and he wants me to get a catch can b/c i'm getting oil pushed in my eng. Be advised that this is a conservitive tune so i don't blow it up. I'm sure if i said "**** it Jr blow the **** out of it" Then it would be much higher but not for long.

There's nothing wrong with a 365 WHP car on a conservative tune. Those are fun to drive!

That powerband is awesome!

what brand injectors? what brand FMIC? Did you change your fuel filter when you did the Walbro (or ever)? Is it the original? I changed my in tank filter the same time I did the Walbro and with only 30k miles on it it looked pretty bad.

bunch of checks you can do for free....or pretty cheap

1 - plugs
2 - compression (tester is $10-20 at any autozone)
3 - leak test (need a compressor and something to plug your intake...like the bottom of a cup)
4 - bov spring - may be able to find a cheap spring to increase the spring pressure in the bov.
5 - clamps (buy cheap clamps from home depot and clamp all your vacuum hoses)

Sounds like you're going lean if they're all worried about the fueling. Not many things cause that condition....

bad fuel pump
post maf pre turbo leak - sucking in unmetered air = lean
bad/clogged injectors varying fueling between cylinders
bad fpr

Gotta do your regular maintenance and upkeep before pushing the car, for sure. Get that o2 sensor, make sure your fuel delivery is safe, etc etc. Then you can rip it

Just out of curiosity, what tires are you running?

Well i just found a leak. One bolt was not tight on the tgv to the heads, and as soon as i bolt it tight no more stalling. And i had no idea that mt front 02 was bad. No check eng or anything. Jr in the end came up and said hey you need a front 02 from the dealer. Thats going to run me good $200

Just to clear up a few things.

The fuel pump was whining bad... No issues with actual fuel delivery.
The Helix injectors SUCK... They always have, and always will.
The Blitz BOV was blowing open at low boost and idle.. Weak spring, probably just old and tired.

The blowing up comment had nothing to do with fueling/tune.. It had to do with a crankcase line that was hooked up wrong and was basically sucking oil out of the crankcase and into the inlet. The oil was getting into the intake manifold, and obviously into the CC chambers.. Gas + Oil = detonation = blow up.
So I told him not to beat on it until that is fixes to prevent it from blowing up
