Its an ok product its stock fuel settings are way to lean. And it is very vulnerable to water ive had to clean it and dry it a few times while i was riding in the rain cause it started glitching out and changing my tune settings. Honestly i wouldn’t recommend this product.

Ordered this tuner with the evo u slip on and the slip on was not made properly to fit my bike..Tuner works as it should from what I can tell. Was easy to install. Customer service was garbage will never order from them again.
