I need some advice from someone familiar with 07 GSXR 750. It's obviously an older bike but pretty healthy. I went from oem headers and slash cut with a PC 3 street version and switched to Arrow full exhaust with a flash tune...I actually had the thing flashed twice because I just felt it was lacking and not as fast in the straight. Restrictions are noticeable but that's it. I'm thinking of going back to the PC V this time. So can I run both flash and pc without conflicting each other? Could a fuel map be loaded to the ecu? Kinda lost now and the ones doing the work are taking my money.
