It looks like it a problem with the ignition advance. Stock car when cold runs between 30-45 degrees of advance as you tip into the throttle below 2K RPM. With the Osiris ROM it's running -7 degrees right up to the point where the engine actually starts to rev up. We've got a few things to try, but we can only run 1 or 2 test before the car is up to temp and the problem goes away. I'll post more tomorrow when the car has cooled off and we can run a few more tests. Jared@UpRev.com
