Better fuel economy?
I own a stock 2004 Ram 2500 with the 5.9L HO Cummings and I was looking for a cheap way to increase fuel economy and was debating on getting a programmer from Ultimate Tuning and Performance but I don't know much about this brand. The website claims to increase up to +50 horsepower and +60 ft. pounds of torque while getting +5mpgs. Does anyone have any input on these? Attempting to avoid forking out hundreds of dollars on an air intake and exhaust.
