JB4 need help!!
I just went to the dealer to replace my battery the other day. Everything was working fine before I took my car in. Got my car back and now I'm not hitting full boost in map 5. I hit around 11-12psi and I'm running e85. Before I was hitting 15-17psi. What is going on? No codes either.

Call me a newb, but if the dealership replaced the battery, disconnecting the old one and taking it out and putting a new one in, that could've potentially kicked you out of map 5 or done something funky map/adaptation-wise?
Either way, I'd get on a straight stretch of road and get a couple 3rd gear adaption pulls to help hone things in. Even after that, drive it for a couple more days to help the map 5 learning process, just to see if it learns up beyond the 11psi or so you were hitting. Also, if you could provide a log that would be sweet.

+1 for logs and wait a day for map 5 and get some runs at WOT.
