Top Speed???
i was wondering how fast a f150 is suppose to go lol. i have mine and i only toped mine out at 105. i was curious bc my bullydog programer is suppose to override the governor on it so i'd expect it to at least hit 120. but when i toped it out it wasnt like it governed out it just hit 4 rpms and stayed there and the speedometer stopped at 105 and it just ran like that till i let off the gas??? o and the speed limiter is set at 180 even tho theres no way it will hit that but just throwing that in.

With the gryphon and using a tune(canned/custom) along with custom options you should be able to overide this and make it stick.
Don't ask me how I know!

Maybe, the rev limit is too low?
Didn't Bill get up to around 122 on a track in a tuned 150? Maybe it had more bells and whistles than just a programmer though. I'd really be pretty leery though about taking a truck to those speeds on ordinary roads with ordinary tires. I think you're asking for some serious trouble. - Jack

With my old 03' f150 when I attempted to go speeds higher than 100. I aways was on a closed course or drag track and followed the tracks minimum requirements which one of them was having tires and rims rated for those speeds.
My 03' was also a 4x4 which is a bad thing also when you go over 100. Most of the components on 4x4's are not rated or even tested for sustained speeds of over 100. Usually the quick runs of "let's see what this baby's got" won't hurt.

The 5.4L shouldn't have any problem hitting 120. The trip we took in Gator's truck at Talladega had us at 122 and that was only one lap. I'm sure we could have pushed a few more MPH out of it, despite the fact that it's like pushing a brick. There wasn't anything special about the programmer. Just a run of the mill Gryphon.
As mentioned, make sure your tires are rated to exceed 100 MPH. For more information on tire speed ratings, visit How to Read Tire Ratings

I have personally seen 134 out of a 05 Supercrew King Ranch with the original Edge tune. Not at liberty to discuss where or when. But yes, 120+ is and does happen.
