egr dosent cause a power loss, it just looks ugly on a clean engine. the 6.0 is a low emision heavy duty engine and doesnt need egr to make it pass emmisions. the computer has to have the egr dtc's turned off. (either send the computer out to s&p or find somebody w/ls1 edit tune programing) on a 4.8 the check engine light will come on driving down the road without egr. if you want i'll give you a complete 6.0 intake w/6.0 injectors(it has no egr inlet), 6.0 exhaust manifolds, intake gaskets, exhaust gaskets, hummer h2 air box and inlet tube FOR 100.00 + SHIPPING... you then can tune the computer for the 6.0 injectors and no egr... your on your own for that i know
www.hotrodlane.cc has done that before. they get 250.00 to program a pcm and after that you can send back to have it changed for free if you ever need it as many times you need to.
