Is the Synchronic DV kit worth the extra cost? If so, why?

Nobody has used Synchronic’s diverter valve? It’s supposed to be the best on the market.

 

I have one on my car. It has incredibly fast response but that it caused some minor drivability (smoothness) with my tune when transitioning out of boost in part throttle.
Personally, if I had it to do over I'd go with a Tial QRJ.

 

There’s no way to adjust it?
