Exhaust leak? That's a lot of black **** on the hood.

196/174 @ 12psi is not all that bad considering the 2 1/4" exhaust, and the crazy rich up top. I lose power on my car due to 10.8 afr's on the top but you completely flatline at 10:1 afr's. You could gain 15whp up top jut by leaning it out and another 10whp from a 3". That puts you right at 215-220whp right where you should be.

Exhaust leak or oil burning off the turbo. My hood has some black on it too.

That black SRT4 needs to rip off the duals. I did it to mine, weighs about 12 lbs. and eliminates that sloppy fork in the exhaust

Cool pics!

the more i look at your charts the more I wonder why it spools so slowly. It has to be in your 2 1/4 exhaust. When I had the S60 on my 1.6L I had a full 2.5in turbo back w/ no cat. I would see 12psi @ 3700rpm and 18psi @ 4100rpm.

on the street I see 12psi at 3.8-4k...but I dunno how accurate both are. when I do an exhaust I'll go back and see what it does.
