[s-cars] Re: wrt pushing RS2 to the edge...

  I have also been wondering if I've been pushing the Boost Enevlope a little
myself.  I have installed an additonal digital(PSI) boost gauge and A/F meter
on my 92 S4.  I'm running Ned's(IA) software on my RS2 setup and
consistently see 28 PSI.  It goes to 28 PSI for several seconds and then
backs down to about 26.5 PSI.  The A/F meter stays well in the rich zone on
WOT full boost.  I've had this setup for almost two years and occassionally
in the summer heat in traffic with the AC on it will detonate then the ECU
corrects.  I'm at 6200 feet elevation running 91 octane.   I've experimented
with Toluene, but haven't noticed much difference.  I don't know if there is
anyway to hear detonation at WOT 4k-6k rpm.  Perhaps it is detonating?
