Agreed ^

but yes for courtesy go back to stock or give the tuner as well.

If playing the odds, I'ld say you're right ....
.... as when I'm looking at cars or trucks when shopping, I tend to walk away from the modded ones fast too ....
.... but when looking at a specific car, it's not so hard to tell a beaten car from a pampered pet of a car that the
owner just likes to "pamper".

I have a tuner for my '07 FX4, but that truck is babied. I like the firmer shifts with no hunting, better throttle
response, and the better mileage that showed itself ain't bad. The tuner will work on our '08 GT as well but I've
not seen a need for it.
