  Looking at it that way, it seems likely that burn would happen sooner and 

possibly lower EGT rather than raise it.

  I removed all of it on mine and Dad's Passats.  We were told that our 
chips 
don't pay attention to an EGR signal (off road use) so no CEL.  Dad has 
stage 2, I have stage 1.  Interestingly his throws an EGR code (light's 
always 
on anyway due to a broken off gp) and mine doesn't!
