Unhappy Stage 2 wrx is slow!?!

Ok not all stage 2 wrx's are slow, but mine sure is!!!

I own a 02 wrx which will be seeing a fairly extensive update in the next week or two.

Current Mods"

turbo back exhaust w/bellmouth DP
TXS short ram intake w/K&N filter
up pipe
mishimoto aluminum radiator
ebay TMIC
worx tuning Recirc valve
Greddy catch can
full prosport guage set: boost, oil pressure, oil temp, egt... exception of wideband A/F
And badlands exhaust dump (seldom used) but interesting!!!

I am flashed to stage 2 using an XPT Stage 2 map boosting a steady 16.5psi

Also im at 82k miles with my maintanance all up to date

Only problem: My car is slow... slow enough that my buddies cobb stage 1 wrx pulls on me tough...

I can not remember if my car was always this slow or what... It seems to run quite well!!! I was just astonished to see my buddies car pull on me so badly. In all gears!!!

My one and only hint of a problem... My car stinks like an Arco gas station when i step out of it. Im talking Massive amounts of unburnt fuel and hydrocarbons. Im told it puffs a nice lil cloud of black smoke too!

I am just at a loss as to why its running so badly...

Next weekend i will be taking my car to Dom tuning after me and my bud bolt on a couple mods... fp18g 7cm with full supporting mods.

I just want to make sure i dont make it overly difficult for him by bringing in a car in need of work.

i will be in detroit all next week and wont get to my car till friday, so ill start tearing into it then.

any ideas that could get me started in the right direction would be appreciated!!!

My initial guess is oil on the maf or a malfunctioning o2 gauge...

thanks everyone!

Brandon,

What kind of Subaru does your buddy have? If he/she has an 06/07 WRX then it WILL be faster due to the larger engine displacement.

^^ true, my guess is that you have an uppipe exhaust leak,look at every exhaust connection and if you see any black carbon around the flanges, its leaking.

why don't you ask Dom? he will be the one tuning it. I know him personally and i will tell you he is very good. except the last time i talked to him he said he was exiting the tuning world.

Dom Tuned 2003 WRX Wagon
251.3 WHP
235.8 WTQ

If it's worth doing, it's worth overdoing

my buddies car is the exact year as mine, with about 30k more miles on it.

I will check for a leak first thing when i get back, what i do know is that my car was boosting a full 16 psi when he was pulling on me. His was boosting 13.3psi

I know boost isnt a good measure of performance, but it is a good way to determine a possible leak.

I actually just got off the phone with Dom, he suggested checking vacume lines.

I'll keep ya posted, let me know if u guys have any other suggestions.

i appreciate the help!
