The motor is all Stock for now. I had a Si computer on it ran perfect. My buddy gave me a Chiped computer with the Stock ZC map now on WOT it bogs down and will hardly move out of its own way. I run about 90% throttle and it prefect. Could this be a bad ecu? or a Bad map?

Thanks for any help

switch back to the original ecu and see what happens...

 

Si ecu works just fine

BTW the Si ecu is not mine I have to give it back this week thus why I am got the chiped one.

 

if it runs fine with the si computer, it could be a bad map.... try remapping it and see what happens
