What kind of mpg increase with tuner???

[HSrider]

Have an 08 6.4L and looking to increase mpgs and performance with minimum mods. Also want to maintain reliability.

Right now I'm looking at intake, tuner and dpf delete.

Truck is completely stock.

Thanks

2-3 mpg gain honestly with spartan 250 tune, 4" afe exhaust and afe intake. And I don't feel like I have to baby it all the time trying to get better mpg. And thats with a pretty new truck. I hope to get even better with more break in.

Same here, Running a 250 Tune and removed the DPF. Stock intake and everything else is stock other than the tuner and i got a 2mpg gain. I have heard tons of people running the 275 tune from spartan and they are getting 5+ gains with exhaust and intake.

Thanks for the information guys.

It all depends on the right foot. I can run my truck hard for a tank and get 13.5-14.0 mpg with the 275 tune. If I take it easy (which is rare) then I can manage 15-16 mixed and 17-19 on the highway.

I gained 1-3 depending on how I am driving....which usually means 1!
