A good way to see what your truck is doing is get a ScanGuage D to see what it is happening when you are driving.

It will tell you more then the gauges in the dash will.
Have you personally used one or had good luck with it.? I bought one for my freightliner with an M11 and it tells me absolutely nothing. Customer support says it's something on my truck but I don't know we can plug the computer in and tell anything we want to so I think it's got to be something in the scan gauge. Actually spent very little time fooling with it. Just figured it was a scam for the money.
