I just got my PV from fuel moto a few months ago with only stage one upgrades. Bike ran so much better it was like a different bike with the tune Jamie sent me. The other factor in buying from Jamie is that he supports you if you upgrade. Which unexpectedly i am now doing, 103 stage 3. Fill out the online form and a new tune is on its way matching your bikes specs! Awesome and money saving in the long run.
