I'm also interested in knowing. Definitely swapping to a synchronous BOV, but trying to decide which one has worked best for people. I've heard good things about Synapse and HKS.

Just thought I would post this review for those interested. These BOV's were run as bypass valves (recirculated) on my KA-T S13.
SSQV Experiences:
- Would surge at anything less that 3psi
- I tried everything to resolve this including larger signal line, shorter line, dedicated line, loosening spring, softer springs from sprinkler heads etc)..
- Would not open on light load shifts causing surging and MAF overfueling from surge.
- I would assume all this compressor surge is not good for the turbo...
Synapse Synchronic Experiences:
- Bypass valve design allows air to bypass turbo during light load cruising for increased mileage (less load on engine)
- Opens while reving when stationary which SSQV would not do for me. This thing flows a TON of air!
- Cool sound on full throttle shifts..like a laser beam from Star Treck or something, even recirculated
- Light load shifts is whisper quite (*sleeper style*)
- No surge at all, not even during light shifting.
Overall I'm very pleased with the Synapse BOV. While I would cringe when shifting with the SSQV, the Synapse is a relief! It actuates fast like a pneumatic piston even during vacuum, has a push pull design to increase mileage, does not leak (tried to 10psi) and is easy to install.
I have yet to adjust it so there may be ways to transient increase response as well.
Synapse is the real deal!
