Ford Expedition Tuning - High Speed

we own since December 2008 an Ford Expediton Mod. 2004 XLT. Before we owned a Chevy Tahoe. So, the Chevy ws limited at 110 mls/h. The Ford ist limited at 100 mls/h. We want to upgrade. Is this possible ? To which speed ? And must we modify the brakes ? By the way, it has autogas (LPG) included.

Best wishes

Re: Ford Expedition Tuning - High Speed

You want to run a Ford Expedition faster than 100mph? You have a death wish?

The answer is no, there's no easy way to do it. The limit is programmed into the computer. You would have to find someone to hack the computer and reprogram it.

Re: Ford Expedition Tuning - High Speed

There's a tone of programmers out there from anywhere to $100 to $300 that will undo the limiter and make it so you can go as fast as you want until you hit the redline on your engine rpms. If you do this make sure your tires have the proper speed rating and you definitely need an upgrade in suspension and braking. Even with upgrades the truck isn't safe over 120 and if you go faster you are definitely looking for trouble

Re: Ford Expedition Tuning - High Speed

SUV + high speed = NO. I'd leave the limiter the way it is. 100mph is plenty fast, and as mentioned above, you can only go as fast as the tires permit. Should you blow a tire overspeeding, you can run into insurance claim problems as well. You can get a custom engine program installed which can retune the PCM to different characteristics, such as change tire size, delete the speed limiter, and even play around with the transmission shift points.
