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!

so u dont think that bullydog overides it with its top speed limiter???

Ok,
The BD is suposed to be at 120?
And you can only get to 105?
Something ain't right

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.

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.

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.

I have touched 120 here on the autobahn with just a edge. It felt like it had more but my tires are only rated to 112 so I let off.

That's probably smart. Our trucks are not the most perfectly designed aerodynamic masses, and I expect the control of them gets pretty squirrelly at those speeds.
