I have an 03 Sierra, 2500 HD, with about 97,000 miles on it. I am only averaging about 12 mpg and would like to try and get more. What is the best programmer to accomplish this? I also need to recalibrate my speedomiter due to an 8" lift and 35" tires. Help!

I have a Hypertech on my LB7 and I like it. Not the most power and you can't check balance rates, but you can correct for tire size and it really wakes up the truck. I haven't had it on the truck very long, but there are lots of posts on here with guys putting them on Level 3 and just forgetting about them. That's what I did, and it makes the truck run similar to a LBZ.

Just my $.02!
