It completely got rid of all the issues we were having with the bypass wanting to snap shut and make full boost basically any time you went over 30% throttle.
We also added the Kooks/Vengeance race exhaust. The car picked up 5hp and 30ft/lbs over the 1-7/8" headers that were on it. I was a bit disappointed by that. I think it just needs more pulley to really pick up anything more. We're at 18psi.

Magnuson just puts a NOS jet in the vacuum hose. That slows the bypass from snapping open and closed.
