Sounds like a Dawes type MBC. I haven't tried any other EBC's. . .I have a Blitz SBC-ID. I love it. It's performs great and does exactly what I ask it to do. It will cost you about $480 shipped. . .you can get one from mpjperformance.com. It uses dual solenoids so it's fast and I have never gotten any boost spiking with it. You can change the boost setting by just pressing dial, rotating it to the setting you want and then hitting the dial again. There are also 4 channels that you can set up so that you can change between them.
