may not need a new one but you need your reprogramed for the parts and motor you put in

Try Switching the ecu maybe that might help.

Did you perform the original swap with only the unmodified engine and computer? That is the majority of mistakes swappers make.
If you didn't I recommend you reinstall the original parts and recheck performance If it runs right then you need to discuss the problem with Skunk2.
