Im in the midst of getting mine booked in for a stage 2 map at r tech been there with all my card but have you guys got any ideas or reading from befor eyou cars were mapped?.. i have an air intake, down pipe and sport cat, cam followers been done and all the prep work ready but i have a standard cat back system as they seem to flow pretty well?. im imagining youll get an extra few ponies and torque before would i be wrong to estimate about 270ish and about the same torque?. seems to come on boost alot lower down the rev range and stronger since the precat was removed and sport cat fitted?... exhaust pressure seems to push harder out the back to?.
