Subject: [s-cars] Back in an Audi (95.5 S6) - some questions

Howdy all,

I have been away from Audis Briefly, but have had quite a few in the past.
1984 5000s
1984 Coupe GT
1985 Coupe GT
1991 200 20v
2002 Allroad 2.7T Tip

then I decided to get practical and bought a Prius....which I hated.

So last week I bought a unmodified 1995.5 S6 and a modified, but very rough
1994 S4.

The plan is to use the 94 as a parts car and move the upgrades to the S6.

Here are the modifications listed for the S4
RS Manifold
Aftermarket Turbocharger, KKK hot suction, Garrett cold suction
bigger injectors
tuning module

unfortunately I don't have the room to keep a parts car, so it is at my
parents 350 miles away.

First question:
I am trying to identify the "tuning module".  When I went and bought it I
found a sticker that said "tuned by TAP" so I expected to find one of the
hand written notes as listed here:
http://forums.quattroworld.com/s4s6/threads/13957.phtml But I didn’t instead
I found.
3 BAR transducer, and 2 chips both computer labeled.  One on the same board
as the transducer say: AAN LDR 5CC0 the other says AN MOT F2C5  Any idea
what that chips these are?

Second question:
Any harm in switching chips, but not tubos, injectors, maniforld, wastegate
sprint, etc?  I didn't think to grab the wastegate spring, and couldn't
figure out how to get the manifold off. (those bolts at the bottom leave no
room to turn)

3rd question: how would I identify which hybrid turbo I ended up with?

4th question: how would I clean the injectors, the S4 was full of varnish
from sitting a long time.

thanks in advance.
