I installed mine last weekend and the car feels much better now.
My stock 9 bov was leaking at high boost and wouldn't let me run over 25lbs. It was also surging really bad ever since I installed cams and switched to e85.
This valve has solved both those problems and the car drives so smooth.

Hey guys, I just wanted to clear up an urban myth about the Synchronic BOV since it is piston driven.
Since Synchronic BOV is a piston actuated BOV, the question has come up whether or not it needs servicing with every oil change. Or perhaps it wears out over time and stops working as well as when it is new. The piston BOVs and DVs that are out on the market today, unfortunately have generated this false impression about the Synchronic BOV.
Synchronic BOV is a little bit long in dimensions because we specifically designed around this problem. In blue is the valve and the piston is in red. As you can clearly see, the piston is located in its own chamber. The valving mechanism is an actual valve that doesn't require lubricant. Existing piston designs have the actuating piston in communication with all of the airflow. So that with each dump of the BOV, there is lubricant in the system that gets discharged with it. Synchronic BOV does not need to be re-lubed since the actuating chambers retain all of our proprietary lubricant. The lubricant does not evapaporate or fade over time.
And for those of you that may be wondering about the part of the piston that is exposed to airflow, there is a wiper in the mechanism to save lubricant and that surface gets relubed with each stroke of the piston.

Based on looking at the desing of this blowoff valve it looks (this is a generalization) like a standard blow off valve that is used backwards with a second sealed chamber for the piston and modded vacuum nipples for the reverse design.
Just by looking at the CAD photos, It looks like it would remain open under vacuum. Is there a spring in this BOV? What prevents it from opening under vac?

this bov rocks! Hands down the best bov I have ever used, and I have tried them all. Most of you know my setup, but these are the bovs I have used in order from worst to best:
Greddy type s
HKS
Forge RS
Stock 1g
Crushed 1g
Dejon Tool Leak stop kit and crushed 1g
Tial
And of course the Synchronic is #1 for my uses. Best driveability, on of throttle response, no shift delay.
