Pinging on acceleration.

Your timing is most likely just too advanced. Factory sticker might call for 0 TDC but you should be perfectly safe at 5* BTDC without any pinging. I normally run about 10* just fine. Get yourself a timing light you can trust and go from there. If you feel like your timing lights aren't right, try this method and tune it old school style.
