So last weekend I installed a Motive Autowerks 3 port EBCS, and I've been over boosting ever since. I've double checked all connections and its hooked up right. 1 to intake, 2 to actuator, 3 to boost. Even with WGDC zeroed out it still hits the fuel cut just over 20psi (boost target) at around 4000 rpm. Am I missing something? I can post a log when I get home if needed. Really not sure on this one what it could be. Bad valve maybe?

edit:
Car is a 10' wrx with Nameless catless DP and muffler deletes, Cobb ap, forge splitter valve. No other engine mods and was running fine before the ebcs.

Uh yeah. The part where I said "even with wgdc zeroed out". Cut them by 50% and then kept removing more and more, 10-20% at a time when it still over boosted. When it started getting pretty low I tested it by zeroing out the whole wgdc low and high maps above 2400 rpm, and there was still no change.

Sounds like it's either:

A. Hooked up incorrectly
B. You zeroed the wrong maps
C. The device is defective.

You can test the valve by hooking it up to 12v. It should click/actuate. Not much to go wrong with them, its just a coil.

well there's only 2 (high/low) wgdc maps that aren't compensation maps so I think I got that right. I had been experimenting with my tune previously. I'll take the valve off here in a bit and test it and go from there I guess. Make sure its flowing the right way and all. Thanks for the input!

so I found a cut in the brand new vacuum hose coming from the pressure side of the turbo. The boost pressure wasn't reaching the valve. On another note I tried a few maps I had made along the way, and ended up with the Stage 2 OTS map being the best running one. I really didn't have to anything to it, logs look pretty good.
