hi to anyone out there. I have a 08 zx10.I have just put on slip-on m4 exhaust with power commander v and auto tune box. I put a X-TRE box on last summer also.I cant seem to find a map for my bike for slip on m4. pc has a map for full system which i tried, wasnt happy with numbers. MY best run was first one on dyno which was just m4 no pc or auto tune. I got 176bhp and 74 rearwheel tourqe.If anyone else has zx10 with m4 and map could you please let me know what numbers you are getting on dyno and what map you have. THIS IS MY FIRST TIME ON SITE.
