I've got a chipped 2ctq20v avant with the exact same problems as 
described by Shawn.  I personally have never even seen the car reach 
1.7 or above.  The upgrade is an IA Stage 3 that was done in 1998. 
When I talked to Ned from IA he suggested that the hose that runs 
behind the heat shield by the wastegate could have burned through and 
that I replace it.  Of course, not that I've done this yet to see if 
it makes any difference.  However, I did notice that there is a new 
O2 sensor that was patched in (I just bought this car 6 weeks 
ago)...so - as with Shawn's example I am now wondering if this could 
be the problem, or part of the problem as well.  Any help for both 
Shawn and now me would be great.
