fuel effeciency improvement question

[ryanhendrixarts]

hi everyone,

new to the forum and a new owner of a gmt900 - '07 onyx black yukon denali. previously owned an '03 trailblazer, before that a '96 s10 blazer.

on my s10 i installed a hypertech programmer, k&n fipk intake, jet throttle body spacer, and a flowmaster delta flow 40 series muffler. it's been years since i had that truck and can't recall what kind of fuel efficiency improvements i received on that vehicle (although the lift and bfg mt/km's probably offset any improvements i would have noticed).

with the 11-12 mpg i'm getting in-town with the 6200, i'm considering the same mods for the yukon. i wanted to ask what mpg/hp gains other vortec 6200 owners have noticed with similar chip/intake/exhaust improvements.

thank you all in advance. looking forward to sharing mods and photos...

Freakin' sweet ass pic. Love it. Aside from flattery, I'm useless on this thread.

That is a sweet pic. I really have nothing to offer either aside from the fact that I have never experienced a mpg increase with exhaust mods because all I do is romp on it to hear the exhaust way more then if my exhaust were stock lol.

Depending on driving style 1-2 MPG. See my sig for more info.
