[email protected] Posted January 5, 2010 Report Share Posted January 5, 2010 As you all know, I bought my truck while I was still in Iraq back in August. It already had an aftermarket (but crappy) CAI, and 3" exhaust. I arranged to have the Black Bear tune sent for and installed before I ever even laid eyes on my truck in September. When I picked it up at the airport, I fooled around with the steering wheel buttons and brought up the MPG AVG display: 14.3 MPG. Well, it's only gone down from there. I've always been a very fuel-efficient driver (and in my SS I've been as efficient as possible, lol) and from the airport I immediatly made the 12+ hour drive to Fort Riley, Kansas. By the time I got there, I was looking at about 13.5 MPG AVG. After a couple months there, a brand new Volant CAI, and another drive back to the great commonwealth of Kentucky, I am now looking at a 13.3 MPG AVG. This never seems to change regardless of hwy driving, city driving, whatever. I ran 91 octane in KS and now that i'm home I've run nothing but 93. Is this right? Does it have anything to do with the tune? How far back in the driving history does the SS CPU go to find the current "average?" The last 24 hours? Week? LIFE?!?!

LIFE?!?! it depends on how often you reset the fuel calculator Roger. To be accurate you really want to reset it every time you fuel up. As for actual economy, I saw about 13.5 mpg city and 15-16 hwy before I got tuned by Justin. Now I get around 15 city and 18.5-19 hwy if I set the cruise at 65. Hope this helps.

kevinthegreat Posted January 5, 2010 Report Share Posted January 5, 2010 i usually see 14.3 in city and about 18 highway with my wheatley tune. i usually reset mine every time i fuel up Quote Link to comment Share on other sites More sharing options...
[email protected] Posted January 5, 2010 Author Report Share Posted January 5, 2010 Oh Shaun, how I've missed thee... Yeah, I guess resetting the fuel calculator (as soon as I look in there and figure THAT thing out) would help. But still, I wonder why I'm seeing such low MPG even after the tune? Of course, I drive about 80 in the highway, and I know that's not in the "sweet spot" for fuel efficiency, but damnit, I need to be there and I need to be there NOW!!!

2bfast Posted January 5, 2010 Report Share Posted January 5, 2010 Mine says 13.1 - 13.2 at best. BUT, I dont drive my truck like you guys do everyday.

sierra ss Posted January 5, 2010 Report Share Posted January 5, 2010 Mine says 13.1 - 13.2 at best. BUT, I dont drive my truck like you guys do everyday. I just figured everytime I do drive it, I drive it to get 8 mpg lol Same as mine is. I dont give a sh!t about mpg as long as im by myself. It's throttle to the floor and balls to the wall every time i pull out. Cant get enough of that AWD acceleration specially since i got my wheatley tune. My wife not so much. lol Quote Link to comment Share on other sites More sharing options...
