You say: "When I disconnect the EGR the computer cuts boost pressure" How are you disconnecting the EGR? Simply unplugging it? How does your engine "know" the EGR is functioning? How about simply putting a block-off plate made out of 1/16" aluminium behind the EGR and leave it installed? Maybe this would trick the system into thinking the EGR was functional as the valve would open and close but no gas would flow? Just a thought. RT
