I have an ls swap in my CRX and its mostly stock exept for B16 pistons, ported head, and Skunk 2 intake. I had it in my DA bone stock and it ran fine. I pulled it out of DA rebuilt it and put it in my CRX with all those parts. Now it wants to sputter and seems down on power when I floor it. Im still running stock ECU would just those mods throw it off that much??

 

Yup, your motor is dealing with a smidge higher (point and a half) compression, so the timing is not optimal and neither are the fuel maps.

 

Intersting, how would I go about getting a chip burned for it. Guess I could call up the local speed shop ank see if they could handle it
