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.
