Pic of rev limiter gremlin...

I'm almost certain that he meant the speed limiter, but this brings up another point. 3,000 rpm at 110 mph?? What RPM does it turn at 70 mph? Must be an awfully tall top gear, given the 4.56 axle ratios, to only turn 3,000 rpm at 110, no?

REV limiter product the engine
Speed Limiter protects the driver and GM from lawsuits.
The Speed limite is set up based on vehicle handling characteristics at certain speeds, and also on the speed rating of the tires. The larger Bridgestones are rated for approx. 106 mph (no official speed rating required for truck tires); therefore, GM will set the speed limiter to around 5-6 mph under to protect them from a possible lawsuite.

GM sets all the trucks speed limiters at 100 mph (or there about). My 97 K1500 is that way, my wifes 01 4wd tahoe was that way, and like the picture shows, it would appear that the H3 is that way... and probably the H2 as well. I think their thinking is that you don't need to go any faster, and nothing else. It's not vehicle specific.

Many of the aftermarket engine tuners (at least for the older Gm's) usually have an option to set it higher.

I'm leaving the rev limiter as is on my H3. My Porsche with a top speed of 164mph is better suited to bursts of very high speeds.

I do typically run 75-90mph on the freeway in my H3.

I don't own a Porsche, but maybe I could tie a wagon to the back and you could take it for a spin?

First please check the speed rating on the tires of your wagon.

Hmm. I wonder what would happen to those little solid rubber/plastic wheels approaching those speeds. Might need some high performance wheels.
