Supercharged Members - Supercharger Bypass Valves?

What Bypass Valve are you using? How do you like it?
Have you noticed what your boost pressure does when you let off the gas quickly?

In the instruction manual that came with my Paxton Novi 2000 it says Do NOT free rev the engine as the backed up pressure from closing the throttle quickly may damage the supercharger.
This has me somewhat concerned about the plastic Bypass Valve included with the supercharger and wondering whether or not it actually has adequate flow capability.

I would like to hear from you as to what you are using and how well it works for you.

Thanks,
TH

I'm running the plastic bypass valve that was included in the kit. While driving if I'm over 4k rpms and let off the gas it will suck to a -20 boost I'm not sure if that is safe but everything seems good to go with my setup and it was professionally tuned. But I also would like to know if the bypass valve that came is good or if there is something better that i should get? And would it require a tune?

Changing the Bypass Valve won't require a re-tune.
What I'm thinking is that a larger Bypass flowing more CFMs would be better and easier on the supercharger, since it would dump more boost pressure faster when the throttle is closed suddenly.
