Holeshot EFI Supertune Tuning Box

Yamaha 2006+ Gen 2 FZ1

Dale recently teamed up with Dobeck Performance to make available the new totally plug in Holeshot EFI Supertune Tuning box.The Holeshot Tuning box does not require that you re-map your electronic fuel injection to dial in your tune up. It simply allows the user to adjust the air / fuel mixture in three areas. Idle and low rpms, steady cruise, mid range, on off throttle applications and wide open full load throttle. There is also an adjustment allowing you to set when the full throttle fuel curve begins to come in at what rpm. All that is needed is a small flat blade screw driver and some time to play. Dale has spent countless hours on his Dynojet 250 I dyno doing all the pre testing for you, as well as road testing The Gen 2 FZ1 from sea level to over 9600 feet elevation. He achieved a perfect 13:1 to 13:8 A/F under all throttle conditions. These motors make some nice power and torque gains over stock and Dale's tune up really smooths out the mid range response, and still deliver good fuel mileage out on the road. When you purchase your Holeshot EFI Supertune tuning box from Holeshot Dale will pre set it for you, so its as close to a plug and play as possible. Note! Dale's tuner settings match our Holeshot slip-ons or full system, and also work very well with other brands. The Supertune tuner will also work well with the stock mufflers to smooth out the power curve, plus add a little power and torque. Minor adjustments may be needed, depending on the bike, weather conditions and the elevation where you live and ride. Dale is always willing to help on this regard.

Dale also highly recommends a minor gear ratio change to improve low end and mid-range response. There is no reason this motorcycle needs to go 85 MPH before hitting the rev limiter in first gear. The original front 17 tooth counter shaft sprocket is easily changed to the 16 tooth we offer and will make a dramatic difference in performance. Click here for more info.
