AA tune on n52 328i 6MT review

631twentyeighteye · 03-31-2015, 05:44 PM

Stock i averaged around 25mpg on my 90% highway commute, and then 3 stage, headers and tune i average about 26mpg on that same commute. Not much of a difference but driving is identical so it's a solid drive to base it off of. Basically 40 miles of highway doing 70-80mph with about two miles of a busy 3 lane road with tons of lights and traffic.

Long term average on my car reads 25.5 if i remember correctly. Haven't reset it since i got the car.

That's crazy - I could average 28/29mpg 50-70% highway stock, after the tune it isn't much different. I can still manage 32-33mpg 100% highway - I just drive too hard to really get an accurate reading now :P

I was seeing 22.9mpg highway before the headers. Have never seen above 26mpg. City has been as low as 11 but never higher than about 15. I don't drive, erm, slowly.
