I have a 3-way T fitting coming off the big line going to the vacuum reservoir on the firewall behind the battery. Boost gauge, by-pass valve, and 3-bar MAP sensor all plumbed into that fitting.

Phil,
Thanks for the reply but your set up is too wild to compare to mine. I basically want to compare the Procharger to other "stock" set ups to see where they start getting boost and how much they get at different rpm.
So while I have your attention if you start with 16 psi @2000 rpm what is the max????

I'll just do a run in first and see what I get. The truck doesn't shift until about 70 km/h

@ 60mph my truck is running @ 10 inches of vacuum and I will only see boost if I'm roughly over 3/4 throttle.
I don't think you should see any boost unless your in the throttle, that is the purpose of the by-pass valve.

it's not in boost all the time but even part throttle accelleration it'll make some boost if anything past 1/3 throttle

that's what I'm trying to figure out, I still pull right around 18 inches of vac at idle but when I'm on the throttle at all the bypass valve flutters (freaked me out the first few trips) but the truck runs smooth and has lots of low end power that it never had with the leaky ATI bypass valve
