Looks good. You may need a tune for the BoV as it can make you run a bit rich. I had a 50/50hybrid from TurboXS and eventually took it off because of that problem.

No, not a stupid question at all. The air is metered through the intake via MAF. With a VTA or 50/50 BOV, it doesn't account for the air not going through the recirculating tube and back into the intake causing it to burn richer while the BOV is in the open position. It's a split second, but makes a huge different in my opinion. I see smoother shifts and seems that my turbo spools quicker after a shift with the factory BPV. Now I forgot to ask, is it a full recirculating BoV, 50/50 or VTA?
