You said NO boost in power in one post. Then said the Steeda only made 5hp more in another post. I'm not going to argue with the efficiency of the factory intake, and the fact that most these people are seeing HP increase from the tune itself, and not the aftermarket CAI. However, you just cancelled yourself out. An increase of 5hp is still an increase.

Just filled up.
Drove for about 24 more miles after the low-fuel light and "50 miles to empty" came on.
This tank saw about 50/50 city/hwy driving, and I averaged 15.8 mpg
Low-fuel and "50 miles to empty" came on at about 183 miles on the trip odometer, filled up at 207.5 miles and the car took 13.1 gallons
That tells me that the car was thinking I'd be averaging about 15 mpg, telling me I had less than 2 gallons left in the tank at that rate, and it was holding back about 1-1.5 gallons as "reserve"

Totally not worth $300, agree with you on that. Not that it would help your gas mileage issue either. I get awful gas mileage but only do a lot of stop and go city driving. I regret trading in my old car when I have to stop at the pump. My fuel expense has double since buying the Mustang. I don't regret it though when I driving.

I have. 13 GTtrack Brembo 3.73 manual car and I get about 19.5 average. I filled up with premium and drove like I had my right foot amputated and the clock said 23.8 average when I hit my driveway. I did feel like I was embarrassing all the other Mustang drivers out there when a Prius actually passed me. I had to try to see how high I could get the numbers just once. I did a nice burn out today to make ammends to the muscle car gods though. Ha Ha. I'm just under 4 K on the odometer.

Any ideas why? i did 2 Kam resets and it starts back at 325 but drops like a rock back to 190. Car is feels faster then my old modded 2011 in stock form but again 190 is nothing to laugh about for a stock car while others are pulling 100 extra miles then me.
any ideas before going to the dealer would be great

2012 Brembo w/ 3.73 avg 13.2 (204mi on a tank)
if i drive like the old man that i am... or if the wife is along for the ride (65-70mph) i can squeeze out 23-24mpg on a long drive.

'13 5.0 with Airraid CAI, Flowmaster catback and Eibach pro-plus kit. I average 18 - 19 mpg in heavier city mixed driving and 21mpg with mainly highway with a little city. Straight highway and I get 24mpg pretty easily at 75 - 85 mph. If I really baby it on the highway and go no faster than 70, I can get 26.
Now, it was quite a bit worse new and improved every tank until 5k miles.

My milage is all over the place with my 2013 V6. When I'm at college, most of my driving is in town with stop and go traffic, which gets around 18 MPG. However, when I'm on the highway driving to or from home, it's normally around 30. After I fill up my tank, the digital readout on the screen in between the tach and speedometer has said anywhere from 220 miles to empty to 400 miles to empty.

26.0 is the best I've seen in mine to date. I was cruising at 55-60mph in 6th and slowed down for a town when this pic was taken.
2013 Brembo GT Premium 3.31s
I usually average 21-22 mostly highway at 75mph. Have 2200 miles now.
