Reversible tune/ undetectable tune?

[ghazi223]

hi, i know this sounds wrong but i want to
tune my bronco but i dont want to lose my warranty (i know the performance tune does that but u want something else). id rather a custom tune but i cant find any online or any tuners that can do that, i saw pedal commanders too but i want a real tune.
i usually see mustangs with that, or they just upload the stock tune back on the car before taking it to ford, is there anyway to do this??
maybe a obd2 port tuner, or a piggy back tuner?
as long as ford cant tell

What’s wrong with the ford performance config?

For the 2.7

ZFG - you replace the PCM with a custom unit, when you want to go back to stock, replace your programmed ECU with the stock one.

Ford Performance Tune - covered by a warranty. This tune does not need to be reversed. I have over 50k miles with this tune and it has never been a problem.

ZFG is a custom tune and the most power for your money.
If you want to go back to stock, you can just load in the stock calibration. No need to swap the PCM back.
It’s also the most undetectable next to a piggyback tuner.

I'm very happy with my Pulsar XT piggyback. I wasn't looking for crazy power, but it will try to spin all four tires with a decent launch and I clawed back a few mpg after adding 37s.

Install is super easy, so I wouldn't think twice about having to pull it off for service.
