Well since i never got a reply I can now give the answer. Had a buddy do a EGR delete on his LBZ and he runs the PPE standard. It has no EGR codes but it does throw the Intake Air Heater code.
Ppe tunes don't disable the egr. Egr is still enabled. They just modify parameters in it from being active, there for its not searching for egr efficiency.

Yes it is. And i know thats why its on. I asked the question before my buddy installed the kit and I replied saying it throws that code incase anyone was curious if the PPE would block those codes or not. No EGR codes but does throw the IAH code on start up.
People told me that the LBZ throws a code with an EGR block plate and that I would need a fingers stick or tuning. 500 miles later I have no code. I'm sure it's an LBZ too. Vin code d.
