Can adding a fuel plate really increase mileage as well as power to a basically stock truck? If so, which plate gives the best combo? Sorry if this has been covered already...Thanks.

A lot of companies will say that it will increase mileage 2-3 mpg. I don't think i really does though because all you are doing is turning up the pump to flow more fuel. Probably your best bet for mileage would be an intake exhaust and a set of 50 or 75 injectors (good injectors like dynomite diesel). If you want to go cheep with the intake/exhaust you can do the BHAF mod and just add a section of straight pipe to your stock exhaust. with those 3 things you should pick up probably 3-5 or more MPG depending on what your getting now

fuel plates increase fueling potential. They should have no effect on milage (unless you drive with it to the floor all day) and certainly shouldn't increase it

plvaulter06 gives good advise

^^^

plates only change full load/throttle fueling. So if you keep your foot out of it you are fine. If you act an every time you drive you are going to loose a few mpg...

I am now using a home grind 0 plate, still getting the same milage as with the 100 and stock plate...

timing should also help with a few mpg's

Thanks for all the good info. I just have a K&N filter in the stock air box and straight pipe. On a recent 1200 mile trip unloaded, no trailer I got around 19mpg average. I figure that's not too bad. Thanks Again...P.S. Stupid question... What does AFC stand for???

aneroid fuel control... it just regulates fuel at low boost. Turn it up, and you get more fuel before you build much boost. You get more smoke, and a faster spooling at lower rpm which should make for a bit faster 0-60 although your overall power output won't be going up.

if i mostly drive in town (stop and go) and turn up my starwheel is that going to decrees my MPG very much?

Yes, depending on how much you turn it up the worse its going to get!

Any adjustments to the AFC are going to be directly proportional to mileage since it controls the fueling 90% of the time unless you have a heavy foot, then the fuel plate comes into play...

i dont really have a heavy foot so i dont want to turn it up to much but i would like a "little" puff of smoke when i take off. so what should i do to get that?

I have actually seen nearly 2mpg since the 5 plate but I did the BHAF shortly after.(With a good filter my filter minder kept saying replace after a good hard test run) Where I have really seen the change is towing I used to see 15.5 combined towing and driving solo. Now wih a similar amount of towing and solo I'm getting very close to 18.
