I have a 2006 LLY with a MBRP exhaust and a AFE stage 2 cold air intake and a bully dog triple dog programmer. On occasion the truck has thrown the P1404 (Exhaust Gas Recirculation Flow Insufficient Detected). Would the EGR blocker fix this code from showing up again thus fixing the problem? Is it necessary to get the EGR blocker? Any recommendations or thoughts would be appreciated.
