Will getting my 03 4.0 tuned help get better mileage?!

 

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.

 

Wut brand do u suggest?

 

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

 

SCT`s are popular. i run a superchips and like it.

 

Thanks for the info.

 

Sorry I meant SCT not SVT. Must be that SVT Raptor stuck in my head

 

I just tuned mine along with exhaust and cold air intake and a airaide spacer ill let you know my mileage before I was around 14 city not sure freeway I don't drive it much

 

Thanks Boyd, looking forward to your insight

 

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

 

No it was on it when I bought it
