Re: programer for a gas truck?

Throw some 3.73's in it if you have 4.10's. Our Denali XL gets about 17 on the highway at 70. Normal driving is mid 15's to 16, not bad for a 325hp 6.0 than can haul 7 people in comfort. I might have to come see you about a tune Swanny, the new tranny shifts a little hard from 2-1 and more mpg is always better.
