Tried the date change today. Showed that the license and hardware didn't match (no actual changes) so no dice. I only need to change the tire pressure alarm so I'll have the dealer do it with the recall. 🤷
They can both be used, but FlashCal is literally doing the same thing as FORScan but without you typing in the code. It's for people who don't know how to use a computer or spreadsheet.
You're partly right. I'm seeing -4 psi in general and +2 psi peak. It's back to similar numbers from before I went to 37's.
Edit: 19.8 psi when charge temps are under 110. ACT2 running 135 - 165 has to be playing a role.
I didn't notice you had the 2.3, mine's the 2.7.
I was seeing 19 - 21 over the winter. I'm seeing 15 psi on WOT from a stop and 17ish on freeway downshifts. I'm going to clear the tune, install the updates, reinstall and relearn. I'm hoping that fixes things a bit.
I run 91, have one step...
