What's your dyno HP/torque numbers? I'm also curious if you dyno'd before/after the headers. I've heard good things about headers adding some nice torque so this is of interest to me. Also, why are you running such high boost? The VF30 is optimal at around 19 psi if I'm not mistaken. I wouldn't run it quite that high. I'm sure you can but I'd lower it a little and take a small trade off in performance for long term reliability.

Awesome #s at the track!

I must say, 22 PSI scares me, I'm sticking with my more conservative 18 or so max PSI setting for my car, unless and until I go inside the engine to strengthen certain components.

Regarding the header aspect, when I made that addition to my WRX, it lowered my EGT, sounded better, but dropped torque a touch. I was OK with that because I did several other things which helped overall increase torque at that time.

I dynoed 345hp, 360 ft/lbs of torque, but last night the car just didn't feel right. And it wasn't holding boost. On that dyno run, it held my 22psi right through my power band.

I'm not sure about the headers except for the exhaust tone change, because I had it put on with the FMIC. I did notice a little lose in low end and spool up was a bit slower, but I don't know if that's the FMIC, the headers, or contributing to both?
