Well I have a 2003 F250 4x4 Crew Cab (6.0)(3.73's) and when I run my loony tune with a boosted launch ive hit 13.88 in 1/4 mile. At the time I had 33" terra grapplers no level, 4" straight back exhaust no cat no muff, and an airraid intake. But I have moved up to 35" dynapro MT's so I'm sure ive lost a little. I'd say if it's non dually you should be looking at high 13's or low 14's, with a dually and that added weight, maybe a little worse? Then again factor in if it's 4x4 4 door, motto I've always heard people say who race mustangs is for every 125 lbs shave off a 1/10 of a second. i don't know if thats true for these rigs though
you'll llike SCT with custom tunes bud, I assure you! There is plenty of people who can vouch for that, as for who you want tunes from.. I am in no place to offer advice... seeing as I have only used DJ's tunes which is now not around anymore, but their tunes go through "Quick Tricks".
