What Mileage does you vehicle get???

[Dwn4BassAlan]

Since the new ratio went in, I've been averaging a nice 6.5mpg most times. If I do even a short trip on the freeway though, I'm lucky to get more than 5 mpg.

But hey, I can't complain with the way it sounds and picks up lol. I've never had to actually be careful of my acceleration before losing grip in the back, so that's definitely a +.

Used to be about 7-7.5 mpg, dropped down to 6.5 mpg average, or 5 mpg w/ freeway travel.

yay muscle car

2001 Volvo S40 1.9t, no stereo shit in it for now.

220 miles on 10 gallons, all city driving, with a lead foot lmao. 22 mpg city isn't bad for how aggressively I drive.

Yet to take a good highway trip.

For that you must be in the 11s at least 1/4 mile... My brother had a 78 Firebird, 455 0.060 over, single plane intake, quadrajet 750, dual 3 inch and flowmaster 40s, 3.73 rear. Ran 12s and got 11mpg at 70... with air on

OOHHHHH YOU THOUGHT YOU GOT ME DIDN'T YA?!?!??

TOO BAD I DRIVE 90% OF ALL MILES IN PALOS VERDES, STOP AND GO TRAFFIC, WITH AN EXTRA 200LBS OF STEREO/WORK/SCHOOL JUNK IN THE BACK.

WHY DON'T YOU TAKE A LOOK AT PALOS VERDES ON GOOGLE MAPS, TELL ME IF IT SEEMS A LITTLE "ELEVATED" COMPARED TO NORMAL STREETS.

And your brother must be dang good with the foot work, because even with the old ratio and non-PV driving, I was lucky to get 10-11 with even my most conservative driving.

2011 Nissan Altima,

28mpg on a "heavy foot" day

about 32-35mpg with normal driving conditions

get 565 mi on a full tank!!

Just finished putting my system in today, and it drives the same and gets the same gas mileage!!!

I'm averaging 18mpg with the Jeep 4.0 in my "aerodynamic" Cherokee, mostly doing a 55-65MPH commute and some in-town start and stopping. It did help adding a fresh air intake along with high flow muffler and cat back exhaust and running fuel injector cleaner periodically.

Also my dad's 1969 Firebird 400 bored .30 over with 12:1 compression, dual holly 4 barrel carbs, 3" dual exhaust with headers, that runs low 12's gets 21mpg on the freeway because he has 3.08 gears and it hardly brakes an idle in 4th gear traveling interstate.
