Hi Dan -

Welcome to the Quattro cummunity!

How would you like about the easiest 5kCSTQ power improvement you
can find?  Raise the boost from 1.3 Bar to about 1.7 Bar (6 psi to 11 psi)
in less than an hour.

I've made up a batch of wastegate springs to do just this.  First it was
one for my own '86 5kCSTQ and then after it worked real well I had a larger
batch of springs made for others.

I'm selling these for $35 post paid.  Send me your postal address and I'll
mail you one with instructions on how to install it and how to bypass the
ECU's overboost limit circuit.
