i have a 05 vrsca do i need a pc 3 or do i need a race tuner? called local dealer, they said they only stock the race tuner, not pc3, but can get the pc 3 of course. are they just wanting the upgrade cost or are they just trying to sell a better more variable product for tuning. cost for pc 3 is 350 buckeroos. cost for race tuner is 450 . any insight, and /or info is appreciated.
