Is there anything else that can cause pinging besides the timing? Gas with too much ethanol, poor quality gas, etc.?

I am using an 87 performance tune with an AF1 3.0 CAI and true duals straight out the back, 14" flow masters with 2.5" piping and an x-pipe.

I am at -12 for 0-2000 and -4 for 2000-4000 and -4 for 4000-8000. I still hear a very slight pinging just below 2000 rpms, but it is much better. I tried the following settings in order:

-2, -1, -1
-4, -2, -2
-6, -3, -3
-8, -3, -3
-10, -3, -3
-12, -4, -4

As you said, the power seems to be gone, but I am not sure about the gas mileage since I just started changing things this week. I am tempted to just go back to 0, 0, 0 and try some higher octane gas, but I was hoping to get some opinions before my next fill-up.


Thanks,
