I have a 05 GTO Twin Turbo I bought. It has a 2bar custom OS Speed Density tune. When I go hard to the floor from idle the car has a big hesitation and doesn't move. It acts like it wants to die as rpm's drop. If I go lightly down with the throttle and keep going down in this fashion the car responds fine and takes off. Anyone ever run into this issue?
post log and tune.
Sounds like the high MAP low RPM part of the VE needs more in it. That's pretty typical of going lean.
