You want the Ford controller, the reason they have to flash the PCM is because of the anti-sway software. The computer uses input from all suspension and powertrain sensors to detect sway and apply the TT brakes as needed, something you will never get with an aftermarket unit, as good as the P3 is.
I agree you would think if you have the trailer connector it would have the controller...maybe the chip shortage played a factor and it got shipped without it? At any rate, with the $$ you have wrapped up in that new truck, spend a few $$ extra to get the Ford controller and have it programmed in, you will never gat the level of performance otherwise. Write the check and enjoy your new truck!
Side note, did you see the video posted here of another forum member taking his 7200 lb TT up Monteagle grade in TN with his little 2.7? Really impressive performance! Hard to say, but it pulled better than my old Suburban with the 8.1L!
My 2021 2.7 is faster than my old 1967 Camaro SS/RS 350. 325HP 400 LB/FT. "It's got Twins!"
On spring trip North presently..
