Gas mileage on truck with engine modifications?

i am looking to buy a truck and i found this sweet lifted truck with 38 inch tires and i saw it has engine modifications its a 5.2l v-8, with electric fuel injection, holley throttle body spacer, k%26amp;n air filter, headers, dual flowmaster mufflers with turndown pipes, superchips programmer, and msg ignition and wires



i really dont know much about any of that but really like this truck and am wondering how much of an effect any or all of that stuff will have on the gas mileage



if anyone can help me it would be greatly appreciated



thanks,

With those tires and mods.. your gonna get around 7~10 MPG.. Stock 4wd Dodge ram gets 12~15 with a 5.2 I've owned a few Ram's and Dakota's over the years..Gas mileage on truck with engine modifications?
If your looking for a mod tr get the dodge diesel they are a lot better on fuel. Unless your mudden the 38 pull real hard. i have 315 on my 04.5 3500 swb auto 4x4 2"lift in front 100hp

Quadzilla chip.ram/air induction airaide filter.20 mph hwy. 17city. The tr your looking at will cost you a fortune to feed.If your on it 6 to 8 maybe 10 hwy.Not good if you drive a lot. Also how was this tr put together pro shop or back yard.How hard was it used off road??? have a 4x4 shop check it out there are a lot of parts %26amp; pices that can have issues. There is no warranty with all the mods added to this tr if it current model. Happy 4 wheeling.
