    Default How can i imprve gas milage in my chevy 350

    I have a 88 sierra with a 350 tbi. It is hard on gas! I have 33 inch tires on it and 2 inch lift. I want to know if i can do anything to it to make it better on gas. I flipped over the air breather lid and it seems to have alot more power but will this make it worse on gas?

    I hate to say it but you're pretty limited as you can't readily electronically tune your truck. Smaller tires, removal of the lift, and driving as easy as you can are about all I can think of that'd help -- and I'm sure two of those three things are unpalatable.
