I didn't know this but I thought I would share the info...

I was discussing my drop in boost at the top end, with Hung at ExtremePSI. He stated that all boost controllers have a maximum that they can withstand. I'm still convinced that my flapper is blowing open prematurely. My Hallman came with the GSX when i got it. It's the older style of Hallmans that I would guess is at least 4 years old. Just MAYBE it has a lighter spring in it or the spring is just plain worn out. I guess I'll order a new MBC to eliminate this out of the equation.
