Hi....I've been trying to improve the mileage on my 03 Z71 Sierra.
Done all the regular stuff...new plugs, low restriction K&nN filter and CAI, low viscosity oil(5-20) driving slower.....

Any other tips? Will I pick up anything with a tune from a good dyno tune?

With the price of gas, just trying to optimize what i can with my DD.

TIA:think:
