Yes, search. Lots and lots of threads about this. You would have to get a custom tune. Most tuning options include 87 or 91 performance, towing, or economy

start with load reducing items. brake service, wheel bearing in check, tires at proper inflation, tonneau cover, e-fan, no crap in the truck, clean air filter, plugs.

THEN and only then, go consider a tuner.

Most people go with an SVT tuner and there are various people who can tune them.

Just got my tuner, since I recently lifted the truck my shift points were incorrect and the mileage sucked.

Since I loaded the 87 economy tune my truck drives much better, a lot like it did when it was stock.

My shift points are fixed and I'm gaining MPG's

Get a custom tune though, none of the prewritten crap

lol airaid spacer, guess people still buy them cause they read the packaging and "feel" the HP increase
