Just loaded up the stage 1 93 octane map. So far so good. Did a little 3rd gear pull to 5000 and spool was good and seemed to be about 16psi if my conversion was correct. It's a little tricky to tell exactly what it is since I have the factory boost gauge, and .1 mpa is 14.54 psi and this goes a little beyond .1. I've also heard from several people that after a week or so of driving with the AP that it feels stronger. Also I noticed it does idle more smoothly w/ or w/o the ac on, which is nice too.
