TAP chip

[Tim Reilley <treilley@gwi.net>]

I am looking at a 91 Coupe Quattro with a TAP chip installed.  It has
58k mi.  Any reason why I should avoid this car?  Could this chip damage
it or reduce the reliability at all?  I know it does not do much to
enhance the performance so I would consider removing it to make the car
last longer and get better gas mileage.  

The car also has the K&N cone and a modified exhaust(straight pipe in
place of middle resonator).  Any help is greatly appreciated.

Sorry to you 20V guys who are getting this twice.
