I have a polaris 800 X2 and I found A genesis performance chip, I am running 27 inch mudlite xtr on my Atv, and lost some power due to the tire size.
Can anyone recommends this chip? is it really effective? Does it have any side effects lol?
Thanks

its not gonna do much if anything at all. you need to reclutch the bike. changing the tire sizes messes with the transmission not with the motor.

What he said.
About the only way to increase the preformance of an engine is let it breath more air.

Get a clutch kit like eggenz7 said. This will let the engine wind more into the torque curve and build more power.
