Wants to run!

Both Jack and I have noticed that slightly harder acceleration gets better mileage. He's got a 5.4L 4wd and I have the 4.6L 2wd so there is definitely a larger variety. I think it is because the engineers had torque in mind when they designed these trucks. Bill usually sets the speed limiter at 120, that is what mine is set at. Look around for a track and I'm sure you can find a way for them to give you access to use it. I've got one within 10 miles and a second within 50.

Oh BTW, I'm going to move this to the conversation area of the forum where other peope may see it and add their input.

I don't know that Bill mucks with the speed limiter unless you ask him to. He didn't with my tunes, but it was an easy change using the "Custom Options" menu.

Then, after setting my speed limiter to 110, I set my speed alert at 85, so I don't get a ticket! Does this make sense or what?

I certainly don't want to cruise in the "ticket me" range and, I don't want to push the tire limits, (even though they are rated for 114). But, if I have to go fast for some reason, I most emphatically don't want the truck's brain to shut me down.

These trucks certainly don't need to be "babied", but they don't need to be "beat all to hell" either. I think either approach can be bad for their long term health.

I had an 05 F150 STX 4.6 I only had an exhuast on it and i still noticed the same thing about it. In Ga on 75 S you can open it up a little due to the Speed limit being higher and I always got great numbers going to and from Atlanta

Jack, you are so right; abuse will definitely reduce the life of your vehicle.

I used to harass a couple friends who beat the daylights out of their cars. One had gone through several engines, transmissions, and even the rear end all the while I still had all the original components in my Buick, which I regularly ran pretty hard. Sure, My Buick wouldn't get up to speed as quickly as his Chevy, but it could run at speed with it all day long.

As my dad had pointed out, there's a difference between running them hard, and abuse. When I refer to beating my truck, I just run it harder than usual. Out of all the vehicles I had, I only broke parts in one vehicle -- and AMC; which should explain why it broke.
