No. Ultimately the PC does a more the same thing as the Kev mod, but does it specifically for any given engine speed and throttle opening so can be tailored exactly to your power/economy needs, and more importantly the bike's state of tune. The Kev mod changes the fuelling by a fixed amount (depending on manual adjustment of setting) regardless of throttle position/revs.

Bear in mind, both only affect the open loop fuelling which on post 2007 XTs with O2 sensors fitted. A Dynojet O2 Optimizer or Kev's O2 Controller need to be fitted in addition to adjust the closed loop fuelling. It is usually the boundary between open and closed loop mapping that causes the jerky throttle/surging on O2 sensor equipped XTs. This is where an O2 controller/optimizer helps.

What year is your XTR?
