took my truck back to stock installed switch enabled terrain management reinstalled tune no problem still there.
Damn. Best I've gotten stock doing Orange to SD was 25mpg. I was pretty thrilled with that.Got mine installed a week ago. Definitely stronger. There’s a hill on my commute where the truck would always downshift to maintain cruise control speed. Now it just keeps on going in top gear. Also averaged 31 mpg on a 95 mile trip between LA and San Diego.
I put 285/65R tires on mine and with the crash bars removed no issues. I was told by Ford Performance that the tune would not void the normal 3yr/36,000 mile warrantyhttps://www.levittownfordparts.com/sku/m-9603-reb.html
I just ordered and am waiting for the Ford ECU tune. Question on wheel size.
Will 285/70 void the warranty? The below says 265/70 is max configurable, some have interpreted this to mean going bigger than that will void warranty.
I really want to do 285 and have removed crash bars, but I also want the FPP tune and don't want to void warranty.
