Back from the grave as I'm also curious if anyone is running a blow-through MAF set-up. These rigs are very popular with the big-turbo DSM crowd as the factory blow-off valves are easily overcome at high boost but the MAF can't account for the lost air from venting-to-atmosphere.
I'm hoping to run a TiAL Q BOV on our 930 build, but we're still trying to decide where to mount it along the turbo plumbing. I've got a Kokeln that had an HKS SSQV welded to the end-tank, so we could just weld the TiAL flange on the end-tank in place of the HKS flage. We shall see...
