FP Tune (2019 Ecoboost Mustang)

[2019EcoStang]

Is there any way to confirm the tune is on the vehicle? I had it popping out 23 psi with the tune and then Ford need to replace parts of my transmission and I'm getting the hunch they reflashed the computer because boost is now only hitting 21.7 (and not even consistently) How much boost should my car be making in the cold like 0 to 7 degrees celsius? My car used to make 23 PSI when the temperature was in the 15-20 range when I first got the tune.

Cheers

I'm also peaking 1-2 psi less in colder weather. It's normal, you're fine. It's programmed to reach a consistent torque target, which means more boost to compensate with hotter charge air and vice versa.
