Low boost?
About 2 months ago I had a wastegate rattle problem (identified by the dealer) and they performed the first step in the SIB - software update from the original 29.x 2007 E92 software. Afterwards the car definitely sounded better (exhaust note), but it felt a little weaker on the WOT pulls than prior. Unfortunately I didn't have anyway to check the boost prior to or right after the change. Recently I got a kiwi wi-fi and Rev on my iPad. I took a few measurements today and was really surprised to see the max boost was ~2.7 PSI. Is that anywhere close to normal? Below is the data from the Rev software.
Note - I'm bringing it back in next week due to the wastegate rattle problem persisting and plan to mention this. Just curious for thoughts from others.
