Alright here it goes I have a 98 LS1 Z28 I put a BBk 80mm throttle body on it car had no hesitation problems before now lets say i'm goin down the road at 40 regular then when i mash it to the floor the car now dont accelerate at all then all of sudden takes off. Has anyone else had this problem and how did they fix it???

 

check the TB set screw that holds the blade open a little bit. Im running this throttle body and it has giving me nothing but trouble

 

Already set it and its still running horrible i think i'm goin back to my stock one and just gonna have ported....

 

ya thats the best idea, im saving up for the fast 92
