i do have an idea..... maybe your staging is off your running out of primaries ????
sandors car did that and was going lean he was using 550/1000's
i think he went to 800/1000 and it fixed the problem

I am currently looking for an acceptible replacement. Possibly the greddy 720s. Anyone have experience with them?

Well, for one ping only? I dont think so. Although I can re-adjust it if you think that could be a culprit. I am kinda grabbing at straws right now.
I was always under the assumption that the primaries could supply enough fuel for 10 PSI, but from what Vosko is saying, maybe not. I wish I could get to a dyno, but even if I replicate the problem on the dyno, I am still risking the possibility of another ping. And that one might be my last....
Thanks all for your advice so far! I appreciate you taking the time to help me with this!

OK this is complete random. I don't see on your sig what kind of clutch you are running.
THis may sound weird but I had a problem like you in which i would hear a ping. I thought i was going to break the engine.
Now, are you running that crappy centerforce piece of crap as a clutch???
LOL
This was my case for the ping that wasn't engine related but it sound like it was from the engine. As soon as I upgraded the clutch, the problem was gone.

The clutch is the ACT street/strip.
As of right now, I am going to replace the primaries with larger injectors. I dont necessarily think that fuel is a problem so much as I think I have a bad/lazy primary. Whatever I come up with, I will post.
Again, thanks all for taking the time to help me through this.

not that this is the cure or anything...but if your gonna upgrade your fuel system a lot like that....its not the best idea to run them off of the stock ecu with a controller.....
upgrade to a standalone, ditch the fuel controllers, and the fcd....and theres 2 things outta the way?
