I went to pass my brother in his Chevy 4x4 and had it made until I hit the limiter. What can I do guys? I have a 2003 f1502wd with 4.6.Thanks!

 

Chip, and buy more insurance while you are at it.

installing a "chip" is the only way I personally know of. I use an Edge Evolution Engine programmer. If I would have researched a little better before buying it I would have gotten a Gryphon, basically it's a modded Edge, you can have more custom tunes installed and it is just a better deal all around. Now I need to find a time they are not busy so I can send my Edge in and have it upgraded. I turned up both the rev limiter and the speed limiter, you don't really turn off the limiters. I have mine set to 200 MPH and it has not kicked in yet!

Be careful though, the limits are there for both your safety and the engines. I don't know for sure when you will scatter a 5.4 but it's north of 6000 RPMs....

 

My 4.6 is limited around 135 mph with factory computer. that is fast enough.

 

I would like it at about 120

 

120 is not gonna happen with a 4.6 and a full size pickup. Get a Mustang or a Corvette or even a CVPI. You will also live longer if you have to stop or turn in an emergency situation.

If you drive it off a cliff, the speed limiter is not operable

I thought it should get 120. My 1979 f100 351m will get that.

 

120+ in a pickup? Why the hell would you want to do that?

 

It's an old thread but clearly the OP wants to win a Darwin Award...
