I have had the S/C with cooler plugs and thermostat installed for more than 10K miles. Recently started to ping, assumed it was the hot weather, maybe bad tank(s) of gas. But, it's been too consistent. I seem to remember someone saying there was a problem with Platinum plugs in supercharged engines. I pulled one plug (NGK BKR6EKPB-11) and it looks fine. Maybe I need to go one additional step cooler. Or, is there an issue with platium plugs and superchargers?

I have hesitated going down the fuel mod path, hoping the SMT-6 issues on the new engines would work their way out. Maybe I can't wait any longer. But I'm a bit confused on all the different pieces of the fuel mods...awaiting the cookbook on the newer ECUs.
