Hello guys, i have some trouble arround here.. I have an Euro Ep3 K20A2 with Kpro, ingen cai, kidd racing headers, and when i put some custum inox bpipe with 3" and an Vibrant exaust 3" .. I lose high revs at every gear.. In max speed, i loose 10 km/h ( 6/8 mph ) @ same spot just with kpro, kidd racing headers, custum inox pipe and standard exaust.. I think i need some new map callibraton. All i want is med/high revs ( max: 8800rpms) and i use fuel 95 oct!
