I am using the 40hp tune of the predator along with my Edge. When I loaded the predator tune I did the tire size (stock and stock) and did the speed limiter at 95mph and the tune all at one time. Today I got on it and passed some stupid lady in a Ford Exploder and found myself at 100mph and it hadn't given up yet. What gives? One day I looked at my Attitude for the records and it said I'd gone 101mph. I really don't want to be able to go that fast on the street in this truck. It used to top out at 95mph. Maybe I'll try re-loading it but I was wondering if anyone had a clue to what I did wrong if anything. Thanks.

Did you load a custom tune?.....If not, try loading one with stock tire size and new tire size (stock). Then, check the speed limit option and make sure it says 95. When you exit out it will ask if you want custom tune installed. Press enter and it should work. Mine has always worked when I enter the custom tune mode. Hope yours does too!

That's exactly what I did. I'll work on it some more when I have time. I may just try to reload the speed limiter again.

95 mph? crap, on my 02 GMC 2500HD 4x4 i had the speed limiter set at 250 mph (btw, i never hit it), i wish we could "tune" these like you can the gasser with LS1 edit

I only do that because I have no reason to go faster than that on the highway. It's easy to hit 95 and more. If I were drag racing I'd reset it to the max.
