   Greetings all,
  Since my 83 Quattro has adjustable boost, I am curious how much this 
boost can be increased without requiring computer mods. Does anyone have 
any input on this. 

 Additionally, does anyone know at which boost pressure the computer goes 
into "overboost protection mode"?

 Finally, My quattro requires distributor cap replacement at less than 
700 mile increments to maintain maximum performance. After 1500 miles it 
becomes apparent even at idle. My 83 coupe GT also sufferd from rapid 
distributor cap wear (Excessive deposits on terminals) but it was not so 
rapid as my quattro. Any insights? The wires and coil are new bosch 
replacements and I've tried different spark plugs with no improvement.
Also I've tried using low resistance performance (copper core) wires, but 
the computer senses something is amiss and promptly cuts power to the 
ignition system. (probably preventing me from stupidly damaging my 
EXTREMELY expensive computer and/or ignition control unit).

Any insights into these problems would be greatly appreciated.

Rod Wiggins.
