What is your mpg with your BB tune?

[Nickleahy23]

I got my BB tune about a month ago..its 93 octane, 80% removed normal/100% tow/haul..the thing drives so much better then stock, but it seems like my mpg is gone..All maintainence is up to par, replaced the muffler with a magnaflow and have the tune..i just put in $20 bucks (wasnt on E yet) and i went about 40 miles and now the gas light is on..i was babying it too..mind you this is mostly short city drives, but really? like 5-6 mpg? just doesnt seem right..I guess ill find out what it does on the highway before i look into it..what do you guys get for mpg?

15.5 mpg is the most i've gotten with mixed driving and a full tank on the 91 tune. Short trips will kill your gas mileage faster than a lead foot...keep that in mind, fill the tank, and see what kind of mpg's you're getting

Im gott around 16 Mpg with my K&N intake and 93 octane BB tune driving between Trondheim and Ålesund, loaded with the family on some highway and some backcountry roads... Hows that? The most i got when it was stock was 19 Mpg. Just me in the car, highway and abckcountry roads..

I've pulled 23 on the highway but the tank usually averages out to 17.5-18.2 mpg.

I don't have a tune.

I can get 19 on the freeway, but usually, i'm looking at about 13.5-14 per tank. A lot of my daily driving is on surface streets.

Stock was 13-15 city. After drop, intake, exhaust, and superchip flashpaq it went to 14-16 city. After blackbear tune with current mods I get 15-17 city and 19-20 highway if I'm not doing 100+. Did you change you plugs? Get some ngk v-powers and gap that sh*t to .040.
