I agree with Steve. If you are that worried about the mpg, you cant afford the car. In my case, I could make do buying the car, but I wouldnt save shit on mpg, Id just be better off driving my fox and saving the entire payment.. whole reason for me to not have a new Mustang or drive my old one is to save at the pump.

Change the gears as you see fit and dont worry about the 100 to 200 bucks more a year it will cost ya. Get a better air box or tune and make the mpg up. I picked up 2 mpg on my wife's c5 by swapping intake manifolds, and gained 11 rwhp too. Ha

Back to the op's question. . 3.73 fords racing gear!! With the m6 in town I get 18-19 highway. Low 20's not that mpg matters but it's nice to say I get that high with this performance,

My car was originally a 3.31 gear m6 and I got about 18mpg in the city and 22-23 on the highway at mostly 80mph. I got my 3.73's put in today so I'll see what it does to my mpg, I've also got 20 inch wheels and I think my total tire height ends up being around 26 inches.

22-23 @ 80 with 3.31s? Damn, do you stay in 5th gear at 80 MPH or something? I can get 25.5-26 @ 80 with 3.55s.

For some odd reason I pisked up 2mpg on the hwy after lowering my car. I know it lowers the drag but has anyone else had this?

I've never heard of that type of gain....ever. You do limit the amount of air that flows underneath the car, but I could see 0.2 MPG, no 2. lol

I do have 20's but Ive def seen an increase. Its a solid 2mpg on the hwy. I usually cruise at 80-85 maybe thats why?

Idk. Did you recalibrate your speedo for the taller wheels and tires? If not, you are turning less RPMs, so that may be part of the equation.

re-rx7 · 02-18-2014, 12:21 PM

Well when Ive had the 20's for about 2 months now and they are the same height as the stock 18's. The increase was seen after the 20's? LOL Its really weird.

If they are the same height, then maybe those weigh less than the stock setup. Only other explanation.

Fuckers are light by any means but the rears are close to the same weight.

**pohnjarker** · 02-18-2014, 01:51 PM

When i was NA, i had 3.73s and got 24 on the highways. closer to 21 mixed driving

now im boosted, i have 3.31s and get 22mpg on the highway. closer to 19 mixed driving.

So today I used the mpg avr and reset. To work 16 mph. Back home with adv sport mode activated, got around 19. I did make an effort to go easy on gas. tomorrow I will reset again and run sport mode each way. And drive like my normal self. ( disclaimer) I only drive like 8 mile each way so not much of a test.
