[QUOTE="MD 6.7, post: 1548931, member: 33079"] [b]Tuning options[/b] Tuning seems to black craft now since EPA is attacking vendors of (off road) tunes. I would prefer to ******. But right now might not be an option. What is the best NON-****** tuning for mileage gains? Bought truck used from a Non Ford dealer. Ran awesome was getting 19mpg. Had a new key programmed and suddenly 16???? What gives. Now there’s more turbo lag and she’s thirsty. Regen more frequently! HELP I’m looking at the EZ-Lynk but not sure what tunes or companies to go with! ******d and non ******d? I live in a state without emissions testing after initial purchase. Thx Thx. BTW it’s a 2013 crew cab Lariat. [/QUOTE]
