i put in a #10 plate in about 2 weeks ago and my mpg went from 16.5 to 13, i am not driving it hard at all if anything i am driving it slower to try and get more mpg, i did put it all the way forward. should i put it back more or could i have messed up something in the afc.could putting on intake mods and exhaust help.

My #100 is about halfway, but it doesn't really matter because the governer arm doesn't even touch the plate until full power, or wide open throttle (WOT).
I get 18-20 in the summer.
The AFC housing also slides either way, mines full forward.
I have Amsoil in both diffs and the motor, and will have it in the t-case after the trans gets rebuilt.
