i was wondring if i used a k20 itr calibration is that y my car sputters at high rpm?? where can i find a better calibration. my k manager only came with k20a2/a3 and k24 calibratins.

If the car misfiires at high rpm then do not run it at full throttle or high rpm until it has been fixed. This is very important. Get it tuned.

However, since this is a K20Z3, would this be an engine swap? In that case, you need to check the fuel system and swap wiring before getting it tuned.
