well i've been testing www.bd-power.com new anti bark valve for a couple of months and it's been working great.
Basically it controls the off throttle surge. This is normally present as you let off the throttle during high boost situations, normally under low RPM situations. The basic kit is what is now available the advanced kit should be ready in 3-4 weeks. The basic only protects against surge when throttle is released to a idle position. This should cure about 2/3rds of all surge conditions. While the advanced kit will control the surge dynamically. The valve used is 2" in diameter, and is one of the largest flowing valves produced.
i have the the throttle one and it works great. for everyone with a hx-40 this could be a turbo saver!! you should contact www.bd-power.com for more info. everytime you let off the throttle you get a little swoosh sound from under the hood.
here is a pic.
