186cc ecu

Bike runs great still running it in plenty of power its giving the clutch a hard time now so that next to upgrade more than happy 186cc grom is the go

Flash Works Great

I installed the 186 bbk and a bunch of other goodies on my grom and needed a good tune. This flash works great for all my modifications. From the low end to the high end the power is consistent. Also the communication between myself and the company was top notch. They helped me with all my questions in a fast manner.
