Question saving fuel

I am a first time poster and drive a 1999 f-250 4-wheel dr., auto trans, power stroke...stock...bought new...has 160,000 miles on it. Have been told that putting a chip in will help fuel mileage...I do some towing once in awhile but mostly not. Lots of interstate driving. Rear-end is 3.73 and right now I get 17-18 mpg. Probably will keep the truck another 6 yrs. I,m thinking it could pay me since fuel keeps going up and not likely to come down much. Don,t know what chip would be best and wondered if anyone out there could help out in that regard. Thanks

Chips won't change your mileage that much. 1-2 MPG will be about the best you'll ever see. Freeing up the intake (either DIY or AFE or the like) and exhaust (either straight pipe the factory exhaust or buy new turbo back) and switching to synthetic fluids will give you more gains than anything.

however i think if you do all of theis mods intake chip( dp tuner) and a good exhaust. with a couple of gauges you can see 3-5 mpg over stock drivin corectly

helpful info

not certain I,m confident enough in my mechanical skills to tackle all this tuning and get it right....the dealer where I bought the truck is a good guy but wants no part of this...I live in WV near Ohio and Kentucky borders so I'll start checking around the area and see if anybody pops up....thought I might call DP Tuners and ask if they possibly dealt with anyone in this area or in the Asheville NC area. Thanks again for the replys

the engine gets a little louder when a chip is added. with an intake and straight pipe you can hear the turbo whistle and you'll be able to hear the exhaust. so all in all it will be a little louder. but if you keep the tail pipe behind the rear tire you wont have much in cab noise from the exhaust.

First off, welcome to TDG!!!!!

You'll get very little additional engine noise with those modifications.

Adding intake is easy. Just a few bolts and about 30 minutes worth of time.

Exhaust may best be left to a shop if you aren't comfortable with installation.

Adding a chip or tuner is about a 15 minute job.

DP-Tuner was based in Asheville, NC until recently. They relocated to Northeast GA. You'll gather more information about their satisfied customers online than in any other geographic location, I believe; so ask around and see what folks have to say (or just use the search feature for "DP-Tuner" and be prepared to spend a couple of days catching up on the posts).

I saw a best of nearly 24mpg hwy with exhaust, intake, and Jody's 80 econo tune.

I average 22.5mpg in summer and 19.5 in the winter.
