08' GMC 1500 speed limiter
I have an 08' GMC 1500 sierra work truck that has the 4.3V6 in it. I have been looking for something I could install on the truck to keep the guys from running this thing 80-90 mph down the highway. I would like for it to top out around 70 or so. I see all kinds of stuff to raise the limit but nothing really to lower it that the guys cant tinker with. I went to the dealer where I bought it and was hoping they could just change something in the computer but they stared at me like I had three eyes.

I would think it could be done but the dealer won't be able to do it. You would have to find a tuner and have him change the fuel cut out point. I think they are like 94-96 mph stock?

Re: 08' GMC 1500 speed limiter
I am dumb as a box of rocks when it comes to the newer computer controlled trucks. Who would be a "tuner"?

Re: 08' GMC 1500 speed limiter
Basically someone who has aftermarket software that can hook up to your vehicle and change parameters in the pcm or "tune" it, or modify it to suit your needs. I guess you could call them a reprogrammer also.
