Borla S-Type A/B affecting gas mileage?
I recently had Borla S-Type A/Bs installed on my 2013 GT and after the first couple of days stomping on the gas for kicks :smilie , yesterday, I filled up my gas tank and decided to play it more conservative (for a day or two!) to see how it affected my mileage. I normally keep the display on the gas mileage screen and in typical city driving, I tend to get between 15.5 - 16.1 mpg. Now, it's seems stuck on 15.1, no matter how conservative I drive.
From what I understood, I thought I might see a slight increase, but it seems to be having the opposite effect. Is there normally a "break-in" period??
It's strange because normally the mileage fluctuates quite a bit after I first fill up the tank and reset the gas mileage tracker, but after two days of commuting to work, it seems to be just sitting at the 15.1 mark.
Any feedback would be appreciated!
