I would like to increase my "boost" in my 04' K12GT to Warp Factor 9.8 . I have read many posts on how to increase my horsepower with say, a Staintune exhaust, Rhinewest chip, and etc... . Can some people that have these modifications tell me how much increase I can expect, and who (in your opinion) makes the best exhaust (U. Remus, Staintune, Two Brothers, etc..) and the better chip??. Also, when these are installed, do I have to "re-allign" anything on the motor??. For example, when I put a custom exhaust on my pick-up, I was not aware until after two weeks that it was on there, that I should re-set the computer by disconnecting the battery, and allowing it to stay dis-connected for an hour to re-set the computer. Of course, I use a power programmer now that calibrates every detail right down to rpm's, octane used, custom exhaust, and even tire size to calibrate speedo to correct mph reading. I wish to bring the level(s) up, as I would buy a new GT with the "S" motor, but think the bike is ugly.
