Tried two PC III s in the past on two different bikes. Kept for a short time and sold them on Ebay. Will not waste my money on them again. Yes they were set up properly , by one of their dealers . Problem is if you change anything , it is back to the dyno again. Found out that a good tune up , balancing the throttle bodies , and adjusting the TPS to either lean or enrich did a lot better job. Never heard about the other tools. But figure they are probably the same as the PC III.
