Did you read the stickies?
Particularly "Improving MPG
," "The Nut Behind the Wheel," and "What Doesn't Work?"
Unless your truck is an unmitigated hog custom tunes will not get you more than a half MPG
or so. Split-shot of single-shot injectors: No difference in MPG
I run a one-of-a-kind special MPG
tune and went to single-shot injectors about three years ago. I wish I could report that they substantially improved MPG
, but they didn't.
Don't mess with the engine. If you have maintained it well, its is about as efficient as it will get. Work on the truck. Improved it aerodynamically. Put numerically lower gears in it. If it is an automatic, swap in a stick. If it is 4x4
, gut the front axle and remove the transfer case.
Quit driving like Tony Stewart. He gets paid to drive fast - you don't. So many people post: "I gets 12 MPG
and I drive it like I stole it." Duh.
Don't come off like a complete newbie. Read the stickies. they are the product of a decade and a half of trying one thing after another to improve MPG
We can debate the content of the stickies if you like but at least read them.
