But it really needed an ecu reflash on my 17 KTM 250sxf or it wouldn't really run. Sent to Tokyo Mods For reflash, That helped quite a bit, The terrible 17 KTM battery needed to be replaced for a bigger one. and the TPS had to be adjusted. Now with all that done and behind me, IT REALLY RIPS. im about 190lbs and it really helps my corner speed with that little extra oomph, i also went to 14/49 gearing and its pulling great.Read All Reviews

Definitely increased power low to mid and I would say slightly on top as well. The only complaint I have is I now have detonation when letting off the throttle. I run 92 octane pump gas and never had this problem before. I have attempted to add an octane booster to help but it has only helped slightly. I plan on running some AV100 to see if that solves the problem.Read All Reviews
