We offer our Mycalibrator custom tuning device and speedometer calibrator combo for the 2015-16 F-150 3.5 Ecoboost that would be my personal recommendation. On the 2015+ Ecoboost F-150 the speedometer adjustments for changes in wheels / tires and gear ratios are done through a different portion of the computer systems which our Mycalibrator performance tuner is not able to adjust. So our package comes with both devices which can be used together or separately to improve performance, drivability, and correct your speedometer at the same time. Many of our customers also report better mileage when running our performance and / or towing tunes as well. However manufacturer warranty guidelines are something that we cannot say for certain one way or another, so that would be something you may want to check into with your dealer to see what their outlook would be.

The Mycalibrator custom tuning device has the ability to hold your factory tune and up to 4 custom tunes of your choice. The tunes are available in 87, 89, 91, and 93 octane versions of either performance or towing. Then for customers looking to go even further we also offer optional tunes for higher octane race fuel and ethanol specific tunes. However running ethanol specific tunes would also require our high pressure fuel pump upgrade as well. On the 93 Performance tunes we have found gains of over 68hp and 65tq on an otherwise stock vehicle. I have included some additional information below including a link to this package on our website and a video showing the tune in action as well. Feel free to give us a shout if you would like to discuss this further or to place an order as well and we would be happy to help out.
