Yeah I'd but the tune back to stock. For all you know it could be a tune meant for use with 93 octane, or the tow tune would dump way too much fuel. I'd start there for mpg gains
yeah man your friend screwed you. need to get back to motorcraft parts and get rid of whatever "tune" he did.
I got the ngk plugs cause some of the people I talked to said they felt a difference but I didnt feel shat. I wanna try those e3 plugs if they ain't worth it I'll sell em to a guy I know that loves em and get motorcraft.

My basis was based on the mythbusters. Tail gate OFF not down, and replaced with a net. They tested it with a canopy, tonneau, Reg bed, tailgate down, and tailgate replaced with a net. Sent from my iThingy using Tapatalk
