personally, offroad mode was probably one of the best features on the raptor! i love how it stays at higher RPM for longer periods and how it modulates the brakes when you slam on them and so on...I would never in my life want to lose those features for just a few HP gains....
as what was said, till anybody can prove to me that offroad mode is not affected, no way in hell will i purchase said products.
I honestly do not think these people have utilized their trucks to their fullest potential, cause if they did, they wouldnt be eager to mess with any of its programming. those features to include downhill decent control is bad ass...offroad mode is fun as all hell to use while offroading, especially in 2WD LOL
