What are you guys doing, installing them or listening to MPI.

install a vortex bypass valve.it's worth it.

Doo_ski intsalled a #12 valve on his and it blew his throttle bodies out of the boots.

I too am waiting on this... I have a vortech bypass with flange waiting to be installed, but Mac says NO WAY. Would like to ride with someone that has one installed. The guys at ty4stroke seem to think it is a must. Just don't know yet.

Which is a common problem if they arent put in with a totally clean dry oil free surface, some people do the hair spray thing and cutting the little bushings down on the clamps for a tighter fit.

The blow off valve is a must. smooths it out.

funjunkie--How does it smooth them out?? Idle? or Acceleration? Mine (nytro stage 2) doesn't seem to have an issue with driveability other than stall at idle and rough idle. Thanks

blow off/by pass

Stick with the Vortech, those work just fine

The blow of valve keeps it from makeing to much boost at lower rpm and gives the boost somewhere to go when you get out of the throttle quick.
