Only mods i have so far are JWT popcharger and Helix 3" exhaust. The exhaust is just a y-back.. so what could be causing this? The car seems to hesitate at high RPMs.. i noticed it when i redlined in 2nd and changed to 3rd.. Could it be the AF ratio is off??

 

when you say hesitate what exactly do you mean?

 

I shift, the car kinda slows down for a second even though my foots on the gas, then it picks up again.

 

traction control kicking in i think

 

do you have a manual or auto...

 

manual

 

Could be your rev limiter which I believe is at 6600 rpm's, right near redline. Don't feel bad though, I found my rev limiter at the drag strip!
