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.
 
you should try the colder autolite app103 they helped mine a lot i didnt have pinging problems but it felt like a lot more power to me
 
fuel pressure at idle sounds low to me I get 40 to 42 at idle and my car has the same exhaust as you do.
