HELP! Installed a racetronix pump and new 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 drops @ WOT only to 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.

You might run a smaller gap at your horsepower levels. I have also ran into some bad NGK TR-55s...I recently switched to the TR-55ix irridiums.I took the gap down also. Defintely noticed a difference. Smoother idle for one thing.....and It seems to run better up top as well.

I added more fuel to PE temporarly for a A/f of around 12:1 to stop the pinging at WOT, Ive been driving it around a little thinking I can burn off the excess anti sieze that I might have gotten on the plugs, I'll try to put the A/F ratio back this weekend and see if it pings still, If it does I'll pull all the plugs clean and re-gap or replace them.
