So far, the testing we've done on our dyno for the 2015-16 F150 5.0L has been on completely stock vehicles. Dyno graphs can be viewed under the "Power Gains" tab of this product page.
Vehicle needs to be off in order to switch between custom tunes.
Mods purchased from MPT include free updates to existing MPT tunes. Mods purchased elsewhere can usually be covered by a $20 tune update.
