As far as the pcv tune. His was way too fat for me in the mountains here in Nevada. I had to take fuel away with the pod 300 just to get it to run. If I remember it was - 12,-8,-4 low mid and high. That got me runnable. Also you need a fuel map that goes negative pressure several psi.
My maps are not finalized yet though
Why Go negative Number on pressure table? My boost gauge not go never negative..
