get yourself an SCT XCalibrator 2 from Doug at Bama Chips ( www.bamachips.com )......it will get rid of the speed and rev limiter......and worth the money as far as power mods.....

4wd trucks aren't meant to be driven that fast. There are a LOT of moving parts underneath your truck and particularly with the 4.10 axle ratios you've got, they're likely spinning VERY fast. Fast enough that there's a good chance of something breaking. The speed limiter is there for a reason: to keep your *** on the road with the drivetrain intact. There's no sense in messing with it.
