K,

HUGE difference between 2.0 and 2.5". Even the PCIII maps are significantly changed.

I used the Dynojet canned mapsfor my exact setups going from 2.0 to 2.5" -was OK- but I had her dyno'd when I went to 2.5".

You'll need something - andtrust me, after 15,000 miles and 2 1/2 seasons on my scoot, I NEVER regretted getting the PCIII - very EASY to tweak on your own - free maps - no stealership BS. And it "transformed" the scoot into something with a little UMF!!!!

Just myexperience.
