my 2013 scab has stock tires and 3:31 gears, at 60 mph it's doing 1500 rpm, I'm averaging over 17 mpg around town, I had it out on the highway once when it was 1 week old and got 25mpg, I hauled my quad to work today and lost 1.5 mpg over 30 miles, I know it seems obvious but take out any extra weight you dont need, and beer doesn't count
So I got a set of the msd coils for the truck. Went to install them but one coil I cant get the wire clip to release from the coil. Will it hurt anything to drive it with 5 of the MSD coils and one stock coil.?
I have a 2012 F150 EcoBoost. I have purchased a Roushe cold air input. My question is will the computer accept the change for a smooth transition or is their something I must due for the total install.
