    I have an 03 gmc sierra with a Hypertech Programmer and the hypertech allows settings all the way up to 212mph i think. But I have mine set on 130mph. I have done close to 130 a few times and it hasnt blown. (knock on wood) I love it and would recomend it to anyone. I payed $405 for mine and its worth every penny.

    Stock speed limiter is at 96 on my diesel. I have it set on 200 even though I have not seen 100 on my truck.

    Here is a link explaining tire speed ratings: Tire Tech Information
    I have a Hypertech Max Energy, but left my speed limiter alone. I've gone about 96 and didn't hit a limiter, and I figured I have no need to go any faster than that.
