Just curious if anyone has put an SCT3 tuner (or any other tune for that matter) and has been able to measure/check the difference in gas mileage..better or worse..Im hearing mixed views on that right now.
Thanks

I definately noticed a drop in my city milage driving after having an SCT Performance Tune along with a Steeda CAI installed on my 5.0. Stock I was averaging 14 in the city now it's down to 11.
I took a solid, 1 hour drive a few weeks ago. AC was on, 6th gear with 3.73s, 70 mph, fresh MPG reset as I got on the freeway. I'm using a 93 race tune from Bama. The engine was turning 2,250....and I only got 22 MPG!!
My 07 GT had 3.55s and I could pull 30mpg at the same rpm over the course of a couple hours, same conditions.
I'd like to get my car dyno tuned so I can get the AF ratio checked and make sure everything is happy in there.
Updated mileage report:
With strict, short commuting trips (my office is 2.5 miles away)..and some stop n' go traffic, I get about 11.5-12.5 mpg with my AM SCT 93 Race tune. If I drive along in city traffic that's moving, I can get around 15 mpg.
Kinda a bummer, but....oh well. I don't think 3.73s are really to blame...it must be the tune.
