"It seems to me that this walve would have to essentially take place of your wastegate completely. Why I say this is because it says nothing of the outlet being threaded... Unless of course Im reading the sentence the wrong way "

The valve is designed to "vent", so there is this vent hole. I used a 1/8" hose barb to MIP adapter (Home Depot part# A-85). Cut off a few barbs and punched it into the vent hole (may want to add some thread sealer). The wastegate hose can fit part# A-75 (Flare to female pipe coupling).

So total BM for the boost controller is one pressure relief valve, one A-85, and two A-75. It will fit the exsisting wastegate hose.

I think Dawes device is similar in concept, you may have to make some sort of hose adapter.
