The Banks Derringer tuner is what truck owners are using now to get additional horsepower but also not mess with their factory warranty. The Banks Derringer does not alter any computer settings so there is no footprint at all. It does monitor the throttle and basically add more fuel on top of what is being asked for by the driver.
The install is easy and only two connections. That also makes it easy if something goes wrong and you need to take it off to get any warranty work done.
It has 6 settings for whatever power level you are looking for and up to sixty extra horsepower all the time with no driving issues.
Check out the video on how easy it is to install it and get it going.
