Hi, just wondering if anyone has had their ecu reflashed by an aftermarket company to not only increase performance but to lower engine temperature, and make the overall drive ability better?

Yes it does make the ATV run better and lowers the engine temp I would only recommend it for stock setup though as I'm not completely happy with mine although I did inform the flasher before what mods I have done, it may not be entirely the flashers fault as I have since done some investigating and I think the air box is the problem to restrictive
