Sorry jjennings, this one was all I had to go on and what I was responding to. People above we're confusing a pinging issue with a self inflicted pinging issue. I do know the IAT mod well.

not to change the subject but, why couldn't our cars be designed to burn leaded fuel. If they were we could just go the airport and pick up some 100LL avgas. (100 octane with 2 ml per gallon of tetra ethyl lead and a trace ammount of TCP [tricreasyl phosphate] used to help scavenge lead oxides) It is popular with hotrodders since it is abundant, reliably free of contaminants and less expensive than race fuel.
You could so long as you are cat-less and don't care about the condition of your O2 sensors. Lead gas tends to coat everything with black soot. That's actually the reason it used to be used in cars, to keep a good seal with the valves. Now that we run unleaded fuels in our engines with hardened valve seats, lead is un-needed and can actualy cause harm. A better bet would be to run the 100 racing gases without lead.
