How many miles are on your current injectors? New injectors should increase mileage about .5-1 mpg depending on the health of your current ones, as well as your driving habits.

The truck has about 202000 miles and idk if they ever been changed so it might be a good idea because i could probaly pick up a bunch if there really bad

the two best things you can do for mileage are to keep the RPM's under 2,000, and the cruising speed under 60.

the injectors will probably HURT your mileage.

I have herd stage 1s will give you a 1-3 mpg increse because it's not working as hard to inject fuel

Ya im getting about 17.5 @70 and that was from my house to santa cruz which includes a steep hill climb so i think stage 1s would put me up around 20 easy especially if there all guked up on the inside that would help a ton

Id suggest looking into a little 500-1500 beater car if its an option. It will take a while to recop the $1000 cost of new sticks with a maybe 0 to 2mpg gain. When with a car you will go from 15-17 mpg to 30-35 mpg.

I just bought a little hyundia i bearly fit in but at 35mpg My fuel bill per month went from over 300- to around 120. and I only drive roughly 1000 miles a month.

I love all the tales of high mpg in these big diesel pigs. I have owned my 96' dually 4x4 since 98'. When it was stock with 3.55 gears the absolute best it ever got was 18mpg. I was one of Ryan's first customers and, after installing Bean's stage 1's, Twildman's programs on a TS chip, hypermax 3.5" downpipe, 4" straight exhaust, and an Online Airflow intake, my mpg stayed the same, 17-18 highway, less when driven in town and country roads.

Now, with 4.10's and the same setup, on a 1,000 mile all interstate trip, it averaged 16.8mpg, empty. On the return trip, towing a 24' enclosed trailer, 8ft tall interior height, and 8.5ft wide, it averaged 8.6mpg. Both ways the cruise was set on 63mph.

I have a friend who has the only Dodge diesel that I have ever heard of that gets the mileage he gets. He says that his gets 15 highway. His F350 he traded in on the Dodge got 14mpg. I believe his mileage is accurate.

To answer the original question, I don't think you will see any improvement, if you are intellectually honest.

I don't see the logic in spending $1k+ for hopes of a 2-3 mpg improvement at best. As mentioned above, look into a cheap car with liability insurance - the savings in oil changes combined with better fuel economy would pay for itself far faster than performance injectors would. Btw, the reason stg 1's increase mpg's is because they're single shot vs split shot. The problem is: with stg 1's people usually change to a more aggressive driving style with the newfound power.

To improve your fuel economy in general with these trucks, do simple/cheap things: clean fpr screen, keep tire pressure full, coast to stop lights more to avoid having to accelerate from a dead stop, don't go over 60-65 mph highway, keep your tailgate up or even get a netted tail "gate", accelerate slowly/below 2k rpm, maybe even change your rear gear oil.
