Bokusārēsā : good info!! I usually cruise at 50-65 mph in those designated speed zones (5th or 6th gear), so my RPM does not get that high…..but still sounds like a Auto would beat me out MPG wise… some of the time. A Big.. big part comes to who the driver is/ driving style, light foot or lead foot (no Indians here), … along with some other main factors. |
I was keeping track of every fill up for 2 years.
Didn't really notice a whole lot of difference from stock to header and tune to even supercharged.
It was only a couple MPG difference but I also drove a lot more aggressive, especially after getting the supercharger.
