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.

So you were able to get the timing bump from the dealer and have it stick but not the cobb? And the timing bump made a good bit of diff? I have the AAM tune for my mods and my AFR is 14.7 at idle and in the 12s at WOT. So I wonder why yours are a little off?
Your dealer was fine with doing the timing?
Zeliminator you have the final gear change right? If so who did you order thru?
