[Es2] stock AAN with Dahlback intake vs. chipped 3B

[Mark Wetzel]

I didn't install it, that's part of the overall problem with the car. I
shouldn't say it has a problem, but it's not where it should be.

John Buffum built the car to be an identical twin to his S2 you see
posted in various places. His was built off the line in Germany then
shipped here. My car was built from his spare parts, to the same specs.

Unfortunately the PO decided to "tweak" what John did, and thus I need
to go through everything and make sure it get's put back the way it
should be. Demetris is a very nice guy, I like him a lot, but he doesn't
know squat about the car, and he would hire someone to do this, then
someone else to do that. And pretty soon it was out of control.

I keep asking him questions about why this, or what part for that, and
he doesn't know anything much about it. I've called John a few times,
and I've also spoken with Brian Eckert who was working for John at the
time, but it was a long time ago that they did it. I find that I am
telling Demetris more about the car than he knew himself.

So it's a learning process to find out how it was built and with what
parts, and what it can do as well.

As I figure things out, I'll feel a lot better about it.

Mark,

I know that boost won't happen while revving the engine at a
stand-still. No real force being produced. Keep us posted on what you
find! What condition was your turbo in when you installed it?
