is it nessary
If you want it to run without check engine lights and with normal power I'd say yes. I don't know how those tunes work but they disable the vct solenoids since they don't do anything anymore. I'm not sure how the ECU handles the rest of the timing details.
Appreciate the quick answer. I'm in Canada so would you recommend reprogramming at a Ford dealer ( Trust Issues ) had the Ford dealer telling me I need $900.+ for the certification, truck-only required back discs & pads. Or a custom speed shop?
or there's livernois motorsports in Detroit area.
