Ayy Captain, you're always on the think...
The syphoon chip has code that suggests the egr can open under boost
conditions.  It never occured to me that the exhaust pressure could be opening
it from the other side.  Hmm...  Any harm in setting the "EGR enable temp"
really high, to make sure it is a non-issue, then blocking off the EGR?  You
have me worried that it may be blowing open when I'm already trying to fight
deto under higher (than factory) boost levels.
Nice cone!
