awsf 34p - out/ app2544 - in still pings and I still can't figure it out. Changed the EGR valve but still pings at part throttle. 34p's were in there for about a year before I figured it out. Any suggestions?
P.S. Checked fuel pressure and at idle 31psi, ok? or what? Pretty much stock except for Flowmasters.
