increase fuel mileage???
 

right now my pump is turned up i was just wondering how much it would increase my fuel mileage if i slid my fuel plate all the back towards the ass end of the truck, cranked my star wheel back towards the ass end, and screwed out the "smoke screw" or whatever its called, on the back of the afc? any other suggestions would be helpful thanks

just get lighter on your skinny pedal.... if you do all that your truck will SUCK !!!

ok i was just tryin to find a way to get better mileage casue i was to drive long distances every week. do you know anything about that big air filter from napa? like if it increases mileage or anything

The cummins manual I have says this:
1. Keep engine rpm at or below 2000 rpm
2. Keep manifold pressure below 5psi.
3. Keep exhaust gas temp below 700f

If you have 4.10 gears then running 2k rpm is only around 60mph,which we all know is no fun.:nope:
The '94 in my sig get 13-15mpg running 65+ and 19-21mpg running 55-60. And yes the big filter(BHAF) will help some.

Call me strange.... but..

while i was missing my 5th gear... i had to cruise around in 4th doing 2100-2200rpm while driving long distances...

i think my truck never spent as little..
