I have been running the xrt 60 hp tune for one week now. DPF delete, egr unplugged and disabled. I have hand calculated the milage to be at 19.23. This was mainly back and forth trips to town and farting around. My milage before xrt for this kind of driving would have be right at 12 mpg. I'll run the 120 program as soon as I get the new clutch assembly installed.

Hmmmm. 7 mpg increase :confused013: I get 12-13 mpg max out of the 5500. Do you have a 3500 4500 or 5500 ? I assume you have a 3500 cause I don't see that possible on a 4500 or 5500 because of the gearing.

I would say he's got a 3500 because I don't beleive the 4500/5500 came out until 08 and his sig says 07.5.....

Hey guys,

Yep I do have a 3500, I'll change my sig. The 60 hp tune has been 100% code free. I spent most of the day getting my South Bend clutch in. Holy crap, what a difference. It is stiff, quiet, easy to shift, and best of all it actually works! Not like that dual mass crap. After the clutch install I uploaded the 120 hp program. That Dodge does scoot with this program. I'll run it for a while and report back with my observations. So far XRT is a must have IMHO.

I've got 3.73s and still only get 13-14mpg. Even with the hypertech I haven't seen 15mpg yet. I might have to get a xrt.

How did you get 3.73 gears with the automatic trans? I checked all over the Southern States trying to find a C/C with 3.73 gears and auto trans and was told there is no such thing in a C/C with the auto. I had to either take the 4.10 or buy a regular dually to get a higher gear.

Mine runs around 2000 rpm with the cruise set on 70! Mine is a 07 C/C quad cab 2 wheel drive, 6.7L, aisin automatic!

I called the local Dodge dealer this afternoon and he told me the C/C came standard with 4.10 and 3.73 was not offered with the automatic in the C/C, only the regular trucks.:confused013:
