Hey, guys. I picked up a GSX-R 750 K1 a few months ago and would like to get a power commander for it. It has a yoshi rs-3 exhaust on it, but there's no lean condition on decel and the throttle response is choppy-- which leads me to believe the bike was "mapped" with a YAFMS (yosh box). Is there any way to "zero" the map in there without one? I know the yosh box mapping won't matter once I've had it dyno-ed, but I'd like the freedom to use a downloaded map if I ever need to change exhausts. Thank you for any help.
