Does anyone knows how much is the max boost {in bars} that a Q4 can handle
a} with catalytic converters
and
b} without {removed} them
or
c} with Gr.A {free flow type} one?

I'm thinking for a Integrale 16V "trackday" type map {1.6 - 1.7 bar boost} or for a "1.5 bar costant boost" map. Any comments?

Cheers

Nick
