I have a b17 in my 89 std model with a pwo ecu. I am using a 99 Civic Type R 4-2-1 header. I think that I will use 2.25 in piping, glasspack as a resonator and an Apexi N1. Also I have ghetto intake setup consisting of velocity stack filter with stock b17 tube. Does anybody think that I should chip my ecu? If so with what chip. What about an a/f ratio controller? Any ideas are appreciated.
Thanks
