Guess we should have asked better for what?

Dude! You want gas mileage? you're on the wrong site

 

Really...there's a member on this site that told me he got over 20 mpg on the highway towing a flatbed car trailer, and that's with a 4l80e. I was pretty impressed, but turbo's really seem to increase efficiency.

 

get a good tune first,ditch the programmer. if your looking high horsepower i wouldnt worry about getting great gas mileage

 

Iv asked around people tell me you can have power an gas mileage. yea i get about 22 with 4l60e, straight pipes

 

it's possible, if that's your goal.

 

I think im about to get a efi live custom tune but i dont know yet. im runnin mid 14s with just the programmer

 

Depende de lo que quiera
