Did that. And still get the ping. Added fuel and backed off on timing. Still pinged. It's odd. One above 4,000 rpm at WOT. Is there issues with low pressure at high demand? Or pressure regulator problems. I was thinking if there was a way to bump the pressure abt 4-5 lbs. or would that mess with the stock injectors?
