Installed Sc project crt, need to retune ECU?
I installed a Sc project crt exhaust on my Kawasaki Z800 7 months ago. I've read that need a power commander to reach maximum power. I also read in a bike forum that someone said if i install the SC project CRT exhaust without retunning (remapping) ECU, it'll harm/make damage to the engine, is that right? I'm so confusing!!! After 7 months with ~4000km, whether it made any damage to the engine? So do i have to retune my ecu or just do nothing? Please help!
P/s:Sorry for my bad English.
