Replaced fuel pump and plugs, now I got pinging. I had recently replaced my fuel pump with a racetronixs Plug & Play system and put in a fresh set of TR-55's gapped @ .050 of an inch. I went to test my new pump and Now I can hear pinging and registering KR when I'm scanning at WOT. like before my AFR is still averaging ~ 12.6 at WOT 
. I am not using nitrous right now and it is the same gas and tune I was using two weeks ago with no problems. Is it possible that I got anti-seize on the spark plug electrode and that might cause the pinging? BTW I have not checked the fuel rail pressure yet,Hmmm, do you think I't can be my pump? I will be installing my fuel pressure gage tonight or tomarrow. What do yall think? thanx in advance.

Checked the fuel pressure and the pressure @ WOT is 55 LBS,I feel alot better that it's not the pump. I will clean and re check the plugs tomarrow,It' got to be the plugs or the anti-seize causing the pinging. I'll worry about it later for now It's time to play 
.Thanx for the reply.
