Message: [QUOTE="Morgan@Midwest Diesel & Auto, post: 1144329, member: 8143"] I think your missing how this all works. Your not opening the gate. Your holding it closed until it reaches a desired bp. Your not aclually controlling boost, your controlling bp which in turn controls boost. I think that you are WAY over thinking all of this. And a I can tell you EVERY wastegate I've ever used has had this style regulator. The only other one I have is the hallman and I don't like it. The two port diaphragm style uses reference from both sides. Once the pressure on the outlet side reaches a certain point it will push the diaphragm closed so that pressure will not go any higher. When outlet pressure falls the valve opens and let's more pressure in. It's not a new concept. There are tons of applications out there, millions even that use that style of regulator. How do you think you regulate the air from an air compressor? Same thing. It doesn't creep. I'm not being rude. But your theory or how your looking at this is wrong. Which is probably why you have problems setting your truck to work correctly. Wastegate limits ebp. That is all. You can run a wastgate off all spring if you want. Or you can run it 75% springs and 25% off regulated air for fine adjustment. Which is what we do. On a diesel application you do not need to have boost reference to help open the gate, there is plenty of ebp to open it when it needs to be opened. [/QUOTE]
