RE: Boost Controllers

[Sachelle Babbar <sbabbar@iris.nyit.edu>]

Gary, that's BABBAR. Anyhow, a little trouble on the mc as I did
point out
earlier, but I figured it out and will put into place tomorrow.

Anyway, my controller is manual. I can't speak for those other devices.
What I do is I set my max boost to where I want and I can *easily* dial up
boost (as I have told others) to change handling characteristics (crank up
part or full throttle boost to pull car through turns), to bring up low
end (needed on the mc compared to my old kh). The other thing that I've
noticed is that during warmer times, I have to open the valve more to get
the same boost.

I think Paul Timmerman has a system that uses a pressure transducer. I
guess they all work the same, but it's just how many bucks you're willing
to spend and if you want another bunch of cool looking, blinking lights on
the dash. For me, $12 was (more than) enough. I like my system because:
1. I made it.
2. Don't have to fiddle around to make adjustments. I literally adjust
like I use the tv's remote.
3. It's cheap. I'm cheap.
