I got 320.1 rwhp on a dyno jet and my car is a 7 AT. I have the same mods as semtex except that i have stillen headers,
Im running the Cob tune #s that i got from Denny. Primary fuel and i did advance the timing 2 degress on the cobb but it did nothing. I also change my throtle postion settings.
Acording to the Cobb A/F readings im running lean at diferent rpm bands, but between 6800 and 8000 i picked up at leaset 12 RWHP. the A/f is around 13.6 to 13,8.
Now im not to sure how acurate the cobb is at reading a/f . i also run on Sunoco 94.
i also had my dealer bump the timing By 2 degress with the consult 3.
The difference in the car was night and day. Not sure what changed in the ecu but it made a very big difference.
