Hi, I got a Cavalier 2003 with the 2.2 Ecotec,  SuperCharged GMPP # 1780003, auto tranny.

I got the GM reflash and after 3 different reflash send by GM I'm still having problem;

1- When you hit the kick down around 50 M/H the engine just hit the rave limiter and shift in 3rd gear after jerking a few time at a to low RPM, you can not pass a car that way.....

2- When the tranny is in 1st or 2rd gear at a 0 start, it died for a second and after that it go

Those any of you GM tech out there can gime a clue!!

I know that is not a super V8 car with a LSX eng. but that is my pride, I'm not a tunner car   , it a 4 cyl muscle car I'm building
