Regarding pinging.  A properly operating EGR system will reduce Pek Flame
temparatures which will also reduce pinging.  Engine will run cooler and head
temparature will remian controlled under normal loads.  Note that the EGR
does get bypassed at full throttle.  One more reason to not keep throttle
floored for long period of time.
