WHat I observe is the car accelerate like hell but the boost gauge
never shows more than 3 lbs or so before I hit redline. I could only
get a constant 6.5+ in 4 or 5th gear, which is why I suspect the
wastegate was at work.

I only adjust the waste gate by playing with the screw, maybe mine
isn't working properly, but who knows. I was always wondering whether
or not I am getting the most out of the BBR, and how good it is compared
to the other systems, now I am reasonably happy. I think it fares well
against them.

    Steve:  Your comparison was interesting.  I have also heard about
    problems with the Sebring installation and design.  I also agree that
    the BBR is bulletproof but that it is a pain to install.  Once
    installed, however, there should be no problem.  The Aerodyne system
    sounds interesting and it sounds that you like it the best.  One
    question I had was whether your wastegate is setup up correctly on
    your BBR.  Although you have it set up for 7 lbs of boost, you said
    that it was difficult to get more then 3 lbs unless you went into 4th
    or 5th gear.  In mine it is very easy when accelerating to achieve the
    maximum boost (I set mine at 6 lbs to be conservative) in 2nd or 3rd 
    gear.  What do you think these differences are due to?
    
    Good luck with your soon to be new car and setup.
