Have an 04 zx10. installed a two brothers slip on, k&n filter and PCIII. under heavy acceleration it is missing a bit around 6000 rpms. it surges a bit at idle and pops a lot when you let off the throttle. everything else is stock. I have tried the dynojet tunes which appear to make no difference. if anyone has a good map that would work with my system it would be greatly appreciated.
