JT is 100% correct. I watch his video on the stop and it doesn't move at all. This has made me look at some other areas of the bypass system
Something I do is use a differential pressure calibrator I have and fine tune the actuator stop on the controller. I had a bunch of bleed by after 5000 rpm. This seemed to really help and I gained close to 1 lb more of boost. I just think the factory didn't adjust it real close and not very consistent either. You can also do another trick we did on the lightnings. The actuator closes when you come into boost. I tune it to close at 5 in. vacumn. This brings boost on much sooner and with a timing adjustment at tip in really gives the car killer throttle response.
