- 2020 Mustang Ecoboost, Rapid Red Premium
The FP tuner M-9603-M4C is good as far as the performance improvement and I do feel it improves the shift harshness some but then my 2020 eco premium did not have any harsh shift issues since buying in Dec 29th 2021 at 5800 miles used. So not 100% sure if it will fix any harsh downshift issues or not in a tranny that has such issues. I went with the FP tuner for warranty reasons.
I can tell you if I had known and understood what I do now I would go with a Cobb AP and deal with any warranty issues that may come from using the Cobb. here are my reasons and issues with the FP tuner.
1. My fault for not understanding the changes to the program for 18+ vehicles versus 15-17 vehicles. The program for 15-17 model years allows you to flash from stock to FP tune at will if you have the program installed on your laptop or if the dealer gives you a thumb drive with the stock PC3 calibration files on it, if not using your laptop bring thumb drive of 8+ gigs with you to have them install PC3 file on. 18+ model years FP did away with the ability for the owner to flash back to stock calibration at all, must be done by dealer flashing back to "as built " calibration for a fee. See "note" warning at bottom of web page for the M-9603-M4C tuner, that's what I did read, but not understand correctly. My bad. But in my defense the installation instruction that can be found at the very bottom of the web page under "Procal" still show how to flash from stock to FP and have not been updated for 18+ vehicles but are still based on 15-17 model year vehicle installation.
2. Since installing the tune on my car the configure function of the program that should allow you to adjust axle ratio and tire revolution per mile numbers that will need to be done if you change axle ratio or tire sizes does not work and will not even auto populate with the correct axle ratio and tire size that is on my car. I have a buddy with a 17 model year and he can flash from stock to FP at will and the axle ratio and tire rev per/mile number auto populate with the correct numbers. My speedo and odometer do read correctly. Also, in the configure function there is provision for octane adjustment if you get a bad tank of fuel to help prevent detonation and a misfire diagnostics function that also does not work in my FP program, but which the FP tech reps state should work.
I have been in contact with FP tech for over a month now (5 phone calls once per week) still with no resolution to my nonfunctioning configure function. I have been told they have sent my issue to 4 different engineers so far but no response to my issue or getting it resolved. There are only 3 FP tech reps and they are all working from home so have no actual access to engineers or other resources. The FP tech rep has stated the configure function should work but since my car runs fine and the speedo and odometer are correct, and no codes are being set he sees no real issue with the program in my vehicle. I call BS and FP tech is worthless.
At this point I feel I am just being given lip service by FP tech and will be contacting ford customer service on Tuesday if after I call FP tech one last time and am told the same lame excuse that I will send it to more engineers. I paid good money for a program that is not working as stated it should in the instructions or designed to function.
IMO, DO NOT spend your money with FP program M-9603-M4C unless you have cash to burn.

Also, the inability to flash from stock to FP tune only affects 18+ mustang ecoboosts since 18+ GTs and 19+ Rangers use the newer procal 4 tuner which comes with FP tune software included and allows swapping from stock to FP tune at will. The procal 4 is a rebranded Livernois tuner.
