I was just wondering what kind of MPG's you guys are getting on the 275 tune? I'm running the 210 now and getting roughly 10.6 around town. I just wanted to know if anyone is getting any better with the 275? I know altitude and all the crap will make a difference I just was looking for some feedback. I have an f350 crew cab dually with the full size bed. Also does anyone know with the 275 tune do you need the bigger injectors to run that tune properly?

 

is that with the DPF ?

 

Did you buy your tune for better MPG, or did you buy it for more black smoke and horse power.

If you have to change injectors, you have to remove the cab. I wanna understand. Can you provide more details?

 

I have the dpf and the cat. deleted with the straight pipe into 5" stacks. I had done some reading and some guys are saying that you can get better feul milage with bigger injectors. I'm kind of hoping to have my cake and eat to.More power and better fuel milage if it is possible.If not so be it. The other reason I asked about the injectors was because on the spartan web site on the graph they show the one tune with the injectors. I wasn't shure if running the 275 tune you would need bigger injectors to help compinsate.

 

I cant speak first hand but in many of the posts I have read folks claim better mileage with the 250 or 275 tune when they are able to keep their foot out of it.
