How many miles per full tank are you getting with your SC/ turbo car ? Mine is 150 per 93 tank? Normal ?

I just recently started paying a little more attention in my car. I feel im getting good mpg for my setup. Whipple gen 5 stage 2, driving my normal, with no hot dogging. I get crazy decel popping after i hit it hard, im talking hard. Its my daily and im driving 44 miles a day 5 days a week, but i gotta get gas every 4 days. I try not to wait till im on E either. So i would say 176 mile avg per tank. Could probably get 200 if i took her to the E.

If your decel fuel cut off if turned off (lots of decel popping) that will hurt your mpg. Really should be closer to 20 with mixed city and hwy driving. You can tell if it's turned off when you have it in gear accelerate to 3 or 4k and let off but don't go out of gear. Then watch your afr in the guages and if it doesn't jump up to 20 then your decel fuel cutoff is turned off. Simple fix by the tuner.

Problem is, with DFCO disabled, Emissions will never go ready. That's why most tuners don't disable it. Unless it a catless setup and you request it be on or off. DFCO does save around 5-10% fuel consumption.

I get 250- 300 miles per tank. It's a DD and I do about a 60/40 highway/ city mix. I cruise around 85mph on the freeway and beat the hell out of it on the streets. Usually it sits right in the middle of that range and gets about 16-17 mpg.

I get 100 miles in the city, and 200-210 highway on E85. I'm not shy, I let it eat.

2018 g5 s2 whipple, 93oct, stick shift with 3.73 rear end. I get 19mpg city/hwy mix and 24/25 on the highway driving 75mph.
So everywhere in the 300 mile per tank range.

That is with me driving normal. If i want to be spirited im sure i could get under 200 miles per tank with ease.

I will add that i drove my car 1600 miles home from where i bought it in stock form. When i was NA still i still got 25mpg on the highway. So i didnt lose anything under a cruising situation.

I am about 10-12 mph in the city and 18-20 on the highway. Problem is, it doesn't see as much highway as city.

24 highway in 6th no boost. 15 city no boost. anytime I drive like I stole it it drop to an average of 15/12

New owner, twin turbo on e85, '17 GT, 6spd. Car has almost 1,700 miles on it now, and the lifetime economy is 12.9mpg. Go fast parts were added at about 1,200 miles. I swear I can watch the fuel gauge racing towards 'E'. She's definitely thirsty.

2017 mt82, 3.73's and a P1X. Cruising in 6th on the highway around 65mph its getting 24mpg. Mixed driving is somewhere around 18-20 and all city driving is around 14-15mpg

I seem to be getting about 270ish per tank on my Hellion 20’ GT A10 on 93. The dash tells me 19.5mpg.
My old 12’ GT gen 1 coyote with a Paxton kit on it was getting 22mpg. I think it was easier to stay out of boost on that car though.

I don't care with my 3.55 geared, A10 with a P1X .

You want mileage, get a Prius

When I go back and read the initial post, it looks like the OP is asking why his mileage is much lower than his cousins. In all of the responses, I don't really see anyone complaining about their mileage, but rather, they are just stating what their mileage is. Of course, "none of us" answered the initial question.
