hey guys ive been looking around in hopes of getting
better mpg as well, and as many of you, I''m a truck lover and couldn''t imagine getting rid of my truck or parking it to only turn around and spend money on buying a car. I have a 2007 silverado crew cab with a 6inch lift and 35''s, I have the 5.3L V-8. As far as ive read the K&N air intake system, exhaust system, and programmer seem to help out the most along with driving right... I have the K&N, true duals, and hypertech III, and I still seem to not get that great of gas milage(even knowing its not going to be the best considering I drive a lifted truck). The other day I started trying to lay into the throttle as always, and I started to get about 16 on the highway driving like a grandmaw, and about 14 to 13 in the city..

What I''m wondering is, is there anyother upgrades at all that I can buy that any of you know first hand that will help my mpg out enough to notice atleast? I was talking to a mechanic that has a 2000 silverado and he was metioning a eldelbrock some system
that helped him out about 10mpg... Didnt really grasp or remember what the he''ll he was talking about. But none the less, I just wanna know of anything else that I can add in an attempt to help my gas get me alittle further. I have yet another birthday coming up and my fiance is asking what I want so I figured this might be a good birthday gift(whatever it is)

A 10 mpg increase would be, in a word, RIDICULOUS. I doubt VERY highly that its a 10 mpg increase.

you might want to try headers..... Edelbrock makes headers... maybe that''s what he was talking about?  I don''t think they would give you 10 MPG though

think the only way your gonna get 10MPG better is rip out the motor and put a 4 banger in it.

I got a 2002 z71 extended cab, with offset torsion bars, and i got grill/toolbox, and am running 285/75/16 aggressive A/t''s.
im getting 12-14 city  and 16 highway.
i got the $55 K&N filter that goes in your stock box, and a super 40 single in dual out flowmaster.
did tune up, all new plugs, and wires, felt alot more power, but no help in gas milage, atleast nothing noticable.
it has a vortec 5.3 with 72,000 miles on it.

I get 18.5 combined and 21.5 on the highway.  With the superchips tuner my highway MPG will drop to 20.5.  I have been using various hypermiling techniques and hope to increase my combined MPG even more.

What mileage are people getting in the 2008 models (diesel and gas). I''m looking at getting an 08 1500 or 2500hd, just want to find out what mileage everyone is getting between the two.

I''m looking at a 4 door 4x4 and want to know if there is a big difference between the 4 speed and 6 speed.

2006 Z71 5.3 i got 13.5-14.5mpg with mods in signature plus hypertech programmer during the winter tim (80% city).
just figured up 2 tanks worth for the first time in the summer months and avg. 15.9 mpg (80% city with no programmer). this is going very eas on the throttle. i get my nelson tune on Tuesday. i will run a couple of tanks through it and give the results. Dont really drive on the highway so dont care about the mpg for that.
