ok my friend has a 2006 ford f350 6.0 powerstroke with 51k on it and wants a chip that would not hurt it.
What size tires are you running and how fast do you drive? What gears do you have? I'm seriously curious...I have a Hypertech and have put over 40k miles on it with the chip on stage 2 or 3, even when towing and have never had an issue.
Get 21-22 on the highway pulling an open trailer and 14-17 pulling a 44ft fifth wheel. Unloaded, I have seen a best of 25mpg on the highway. It's 100%, with just the programmer
275/70/18, the factory 4x4 tires. It's a two wheel drive, long bed, super crew. Towing, i stay right around 60-65... 55, if the police are around. without a trailer behind me, 70-75. i have no idea what gears are in it, whatever are factory.What size tires are you running and how fast do you drive?
