1998 GMC 2500 7.4L
I am sending this email to say thank you for the tune you did on my truck. The results were beyond my wildest dreams. I tow a 30' 5th wheel trailer that weighs 8500lbs.My tow vehicle is a 1998 GMC 2500 with 7.4 litre engine. My average gas mileage has been 8mpg towing prior to the tune you did. I just returned from a 9300 mile 4 week trip to California, my average mileage for this trip was 12mpg. I also had an increase in mileage while driving with out the trailer from 16mpg to 21mpg and the increase in power was great when it came to the hills. This was worth every dollar, I saved over 300 gallons of gas on this trip. I would highly recommend this to any one. Thanks again for a marvelous job.
