Personal Intro.- 90QC20V

[Robert Mundo <74237.1355@compuserve.com>]

Hello to all!  I am introducing myself as a mediator for a good friend of
mine who owns a 90 Quattro Coupe 20V.  His Q is Red, 5-spd, 35k miles,
and sunroof.
 
We are curious if anyone has the production numbers of 1990 and 1991 Audi
Quattro Coupes that were imported into the States.
 
Also, one of his only cripes is the lack of low-end torque from his 20V.  He
doesn't get any "real" power until bringing the RPM's to 3k.  What kind of
modifications (realistically speaking, of course) can be made to improve the
bottom-end torque?
 
Please feel free to send me any misc. tid bits on this rare auto.
 
thanks
Rob
