Default Motor governed at 91?

Anyone know about a 2003 ford Ranger XLT 4x4 4.0 Liter V-6 being governed at 91 mph? I need to find out if it is a physical governor or a electronic one.

Electronically controlled by the PCM.

Power is reduced in 3 stages. First, the spark is retarded, lowering power. At the same time, fuel is cut at one of the fuel injectors and the rest of the cylinders' mixtures are enriched slightly to prevent the rush of lean exhaust into the cats. The cylinder without fuel is shifted from one location to another to prevent the engine from developing cold or hot spots. This is called "Round Robin" cylinder disablement. If cutting one cylinder will not stop the acceleration, a second cylinder is disabled at a slightly higher speed and then a third at a slightly higher speed than that, if necessary. (This is on a six cylinder engine, four cylinder trucks only cut out two). Again, this is done in a Round Robin fashion to equalize the heat in the cylinders, heads and exhaust manifolds.

If I ran my truck at 91 MPH I think it would start to shake and fall apart.

Going 91 in a ford ranger is pretty dangerous

It also has a rev limiter set at 3000 rpm

if it has a rev limiter at 3000 rpm the truck would not have any passing or hill pulling power?
i think thats a little to low. but i could be wrong mine will rev up to 5000 when i have to pass or get the hell out of the way on the freeways. might go more just never pushed that far!

91 in my truck felt pretty safe compared to 108

I've had mine to at least 108, It didn't feel bad at all. Lol the deer in front of me scared me but 108 was fine.

I didn't hit him. But he did taste good, and the trooper laughed when he saw why I pulled over and got me to put the rifle down. I got lucky, the joys of Montana.

My other truck, 3 deer and one elk, a cat, idk how many possums, a bat, crow, a couple raccoons its had a bad life lol

you can change it with a programmer or chip, it is there because the brakes tires and suspension are not meant to handle that speed safely

Took mine to 91 once. Ran smooth, but I was more worried about blowing a tire or just losing control. The center of gravity is too high for me to be comfortable doing that.
