ISX Horsepower/Torque setting

[TBraun]

I agree with you on the better set of rear gears. This truck has 1.9 million on it and still has original diffs in it. To me that's a good sign the truck has been driven with sense. If I end up having to replace one of the differentials, I'll replace them both. The engine made 1.5 million before it was overhauled by it was a one owner, owner/operator truck. I think that makes a big difference. Thanks.
