THE FASTEST cars still belong to LMS to date.
It does seem other vendors are improving their offerings, but as previously stated, takes an awful lot of revisions and wear and tear on your OWN CAR in order to achieve those revisions.
Which inevitably leads to more component wear/tear and an even more stringent maintenance regimen than what is already necessary to perform on this platform.
Oh, and Ford Racing installed the AWD dyno's years back into LMS' facility. LMS & FMC have a close working relationship as a result, and YES, LMS does have access to program parameters in the ECM that other vendors do not. This is why, time and time again, LMS tuned cars have been faster, more reliable, and enjoy longevity over the years in comparison to others.
Some have said it's unfair, and some have said not true, but the owner of LMS showed me directly which tables they have exclusive access to, but I don't pretend to be smart enough to remember the technical terms those tables were/are, & out of respect for them as a company, I chose not to photograph the computer screens when it was being explained to me as it is proprietary protected information.
Either way, seems like more vendors have come on board over the years.
But given the depth of involvement that LMS has invested into the ECOBOOST platform(s) in that they offer so many other supportive, go fast products well beyond just tuning (I say "just" lightly) that my own choice has always remained steadfast in their backyard exclusively.
Good luck to the OP in w/e they choose.
