This is an excellent product if you use the auto tuner along with it. The auto tuner allows you to custom tune your bike in every gear and throttle position. you will have to have patience to fine tune the air/fuel ratios. This will take hundreds of miles before you dial it in. No need to dyno your bike. I am totally happy with the results on my 2013 triumph Bonneville. FYI: like with any other performance mod, you are not going to get great fuel economy.

Instructions are adequate. Installed relatively fast. All lights worked 1st time on Processor. Bike starts smoother and now has very smooth power through the gears. Seems to have gained a few horse power and is a pleasure to ride now.
