If you've modded your engine, you need a tuner. Ive been down the road, with cheaper units, that only let you do so much. Do it once, do it right. We run this in our bike in the shop, and its pretty much plug and play. One of the easiest setups we've ran across. Once its set up, thats it. No more messing around with add-ons, and different components. This is the bluetooth setup, you can do all your tuning from the smartphone, eliminating the need for costly gauges. WIN-win
