Tom - I don't see why you guys are saying that 10.5 is going to always keep the PV open. I keep 26" of vacuum at idle. I keep about 20-22" of vacuum at cruise. I keep 12"+ at medium acceleration. <12" of vacuum at hard or full acceleration. I cruise at 13.0 AFR and boost at about 13.2AFR. It's running great. I'll try to get some video up soon

RedMan* - Thanks man. That post really means a lot. Send me a message if you have any questions and I'll help you the best I can. And welcome to the forum!

I just went back through and noticed I didn't have any pics up of the rebuild/paint/reinstall. So here those are.
