Bigger exhaust.
BHAF air filter.
TWC3 2cycle oil in fuel at 1oz per gal.
Keep highway speed at 60mph or less.
Easy accelleration no full throttle starts.
If you have a pyro gauge try to keep your exh temp below 650.
Keep it in the highest gear without lugging the engine. (Drive like an old lady)
Don't let sit and idle when you don't have to.
You will get better milage when it gets warmer out and the fuel is a summer blend.
Your driving habits have more to do with milage than truck modifications do in most cases.

how do you do this?

What you people are calling a TPS is really an APPS Accelerator Pedal Position Sensor (APPS).

Read here on how to reset:
APPS Sensor

Everyone should bookmark Mopar1976Man's site. It has a welth of information on our trucks.

reset, APPS (TPS) Turn key to ignition,(do not start) Depress pedal slowly fully, 3 times,,, turn ignition off, then start your truck,,,,, there are other methods via a volt meter, this is the quick method told to me by a Cummins Tech, if this doesnt help with dead pedel, then there is a code that has to be cleared.

Sorry, that procedure won't work unless the batteries have been disconnected for at least 30 min then re connected.
See the APPS link in my previous post.:S:

I just made a trip up to NJ up 95 and averaged 20 and thats at 75 mph with my adrenaline set at 3

Had you driven at 60 you most likely would have seen 25 mpg. I've seen 25 on my truck highway driving with no load and ideal conditions (flat roads no wind).:thumbsup:
