So maybe you had autotuned map 1 and it went down from target due to fuel/temps, and thena fter you changed to map 2, it had not autotuned yet, so ran the normaly 14.5psi.
I am aware that autotune only does its thing on full boost - this is after significant numbers of WOT 3rd gear pulls all the way to 7000rpm. Map 1 seems to always peg boost at around 12psi while Map 2 takes it all the way to 15. Map 2 feels faster too.
Looks like I also have to upgrade to the V5 software!
