I have experienced this a couple times now. When I get into any kind of deep loose surface the engine will only ramp up to around 2500 rpm. Even when I have it matted. If it would just get the tires spinning a little bit I would be able to get out of the tough spots. Any ideas why it does this. Any way to change that.

 

You're bumping up against the rev limiter, most likely. BTW, momentum is what will get you out of the tough spots. Spinning is just the result of no traction.

 

2500rpm rev limiter?

I'm thinking torque management...

 

Can you program out the rev limiter if that's what it is?

 

Traction control maybe?

 

02s must not have the Traction managment Cause I can spin the heck out of them in the snow or mud..

 

Put your truck in neutral and mash the gas to the floor. Same result as you described? Engine management(rev limiter). You don't need to rev out to max rpms(shift) for the rev limior as we know it for it to kick in. It protects the engine.

A tuner is the only way to remove that.

I believe my truck used to rev limit out in nuetral at 4k not 2500.

 

Um, not to sound cheeky but what gear are you in? Manual or auto transmission?
A buddy had this type of problem with an old automatic Coronet. Wanted to spin the wheels and rev it out doing donuts in a dirt field. Thought the car was gutless... I told him, move the gear selector to first rather than drive. Once the wheels start to spin and the rpm goes up it would shift to the next gear in drive, in first it would rev out and spin like a demon.

 

^^^ This is a possibility.
