yeah I never heard anyone have surging after warmed up being a tps. If it were my bike I'd try removing the pc3 first and synchronizing the throttle bodies. go to R6live.com and look up CephasGT. hell here, http://www.r6live.com/members/cephasgt.html tell him randy (aka serpentracer) told you to contact him. he has a really nice sychronizer he would probably let you come over and do it for you. don't worry, he's a real cool dude.
