ok so I put on a test pipe and of course the CEL came on wich I was expecting because I have yet to install the CEL fix. But for some reason ever since then when I floor the car in any gear it has like a long stall olmost from 2500 3700 rpms before it olmost wants to clear out and go. Maybe could my plugs are fouling out or is the ECU retarding itself cause of the CEL ..?? thanks guys!!!

 

well, your o2's are reporting faults which will mess with the tune. You could try reseting the ecu, but yah need the fix
