Default Hesitation under heavy acceleration

I have a 85 with a new trans 160 deg thermo, performance chip. After the motor is hot some times when i accel hard espicialy in a turn the car hesitates (kinda Pluhhs out for a second) and then is fine. It mostly happens in the turns never noticed it in a straight line? any idea?

...how much fuel do you have in the tank?...fill it up to at least 1/2 and try it again....some of the c4's slosh fuel inside the tank which causes the fuel pump to suck air momentarily and that is where you may get your stumble....common problen due to inadequet baffeling inside the fuel tank......
