Oddly enough, the normal type-H seems to work a little better than the RFL. I cant for the life of me see ANY reason whatsoever for this, they are identical other than the horn on the RFL. But the 3 RFLs I tested had to have an additional washer to hold the same as the normal type-H.
When I dynoed my car with the stock BPV and later with the turboXS RFL, there was no change in WHP and or boost. With the turboXS you just gotta make sure the gasket is lined up properly and you have the correct amount of washers.
