Possible the dealer flashed my truck-6.4

SInce I got my truck back from the dealer for some driveline warranty issues, its running a bit different.. and I mean that in a good way. It seems throttle response is much more instantaneous than before, it seems to get into eco mode more frequently..Oh and somehow my tire pressure warning light is out. I had been running about 65 in the rear instead of 80 and it always flashed me, now its running about 69 and the light is out..( i had mentioned something about the warning on the dash to the service manager when he did a ride along and said it would be nice to not see it) I didn't think you could change the threshold on the newer 2500's? Just has me wondering if some sort of flash was out there for it and it got an update.. I don't have my paperwork because it remains an open case and I was late getting out of the dealer but it is like almost a different ruck? I am going back next week, I suppose I'll ask.. almost afraid they will tell me they did nothing and its all in my head..LOL

Hmm, strange lol. If you can find out if they did an update on the invoice post it here lol. I just had mine in the other week for a rotation and got nothing. They did the standard "multi point" inspection and checked for recalls and updates. Nothing. Who knows.

I should add my TPMS is already reset, but interested in your performance changes lol.

As far as I know, the dealer can't do anything with the TPMS any more with the Witech. Its literally impossible with that tool now.

Yea, all the same things I was thinking..I mean this can't be in my head, its not like I EXPECTED it to run different after pickup..It's just noticeably different..
