First, I should say that I've never used or owned a power commander V. I'm looking to get one since I have an m4 slip on and a k&n air filter. Is it just simply download a map off the PC website and plug and play?. Because since the U.S gsxr doesnt come with o2 sensors, how would it adjust fueling, or is that an auto tune thing that is sold separately. Sorry if I sound like a noob, because I am. Only been riding for 2 years. Also to add, since it hooks up to the tps, will it auto adjust it? My bike also experiences the herky jerky and hesitation on gradual throttle increase in mid range rpms. I've set it to dealer mode and adjusted it while running and warm, but no luck.
