MPG's with lift and big tires
I was wondering what MPG's everyone else who has a lifted 6.0 is getting. I just checked mine for the first time since getting the lift and the 38.5 tires and was surprised to find I'm getting 14.5 mpg city, hand calculated. considering I was only getting around 16 before the lift I didn't think 14.5 was too bad. this is the truck -- '07 6.0 250 SD excab, auto w/ 10,000 miles, no performance upgrades except 4' turbo back with the cat reinstalled but no muffler. I am running 55 psi in tires. how I calculated -- since the speedo is off with the big tires I had to do a bit more calculating than normal. when the speedo shows I'm doing 60 I am actually doing about 66, wich is 10% more. when I pulled up to fill up my trip read 167 miles so I added 10% which gave me about 184 actual miles. divided by 12.5 gallons = about 14.5 mpg. how much do you guys feel I could improve upon this by getting a programmer and an intake or any other performance upgrades?
