04 GTO with a SD conversion. This is a drag car, so when you bring the throttle up to 2200RPM and launch the car will not accelerate immediately it feels like it is on a rev limiter which it is not. No knock, timing is about 24 degrees and fuel is right on now. If you launch from off idle, it accelerates immediately all they way to the first shift. All the problems seem to happen from 2200 to 2800 RPM's and after that is accelerates fine. I don't see anything in TM that is causing it, everything looks good. The only thing I see that is odd is in the OS. It has a upgraded OS in it but it is saying the ECM is a 4.3L V6 but the VIN is correct for the car. This may have nothing to do with or maybe it does and there is something going on in a table we can't see.
