Default Tb

I search the forums and really didn't find what i was lookin for .. But me and my cousin put a 78mm tb on his 2000 t/a and took it to the drag and it only ran a 14.7 , Felt lik it was to big for the car so we took it back off and put the stocker back on ran a 14.14 ... Currently he only has after market k&n cold air kit , 3inch cat back exhaust, superchips programmer, tb spacer.. WHAT IS STOCK SIZE OF THROTTLE BODY ... This car should be running at least mid 13's i would think or am i wrong

Tuning required.

Stock LS1 is 75mm. The stock EFI will be able to adjust for a slightly larger throttle body without any problems or neccesary tuning.

Either you can't drive, or it's time to worry about fixing your car, not modding it.
