poor fuel milage

1996 2500 4.10 gears fuel plate to a #10 when i got the truck it was getting 15 all the time so i ground the fuel plate and it went up to 18 so i thought bigger is better so i took some more off the fuel plate and now im down to 11is there any thing i can do to get better milage i will be silding the plate back because the power difference doesnt compensate for the fuel difference

The plate won't make any difference in mileage if you don't use the extra power. The plate only comes into play when you floor it or under heavy load.

It's all in your foot.

If you can't resist the temptation to use the extra power use a less aggressive plate and slide it to the rear.
