01 LB7 fuel economy

[farnum]

Which chip works the best for fuel economy on my LB7?

[Mark Rinker]

I have had great experience with Kennedy's custom ECM tune for the 2002 LB7 K2500s we own. Our average towing MPG improved by over 1mpg in mixed loads, averaging 6-8K#, usually with empty traier returns. Empty, no trailer miles, which is rare for this truck - are in the 19-21mpg range depending on speed required.

We've tried Diablosport Predator programs as well - no real measurable increase in mileage.

Thanks Mark, I'll check out Kennedy. I was thiiiiiis close to buying a Diablo.
