    At what RPM should I see boost ?

    I finally finished my A trim install. Got the serpentine belt issue solved with an ASP AC delete and used a 90.5" belt. Everything is working well.
    My question is, at what RPM should I start seeing boost ? I took the car for it's first test drive. It was around 4-5 o'clock so there was a lot of traffic. I got into it a little bit but only saw 1-2 # of boost. This was around 2800-3000 RPM.
    Will max boost only occur if my foot is to the floor ? This is my first boosted car, so I really didn't know what to expect.

    you will see a bit of boost at part throttle possibly, but normally you won't see your max boost until peak RPM and WOT
