Nick, Only high load at low RPM, more noticable when its hot. I've retarded the timing and there's no sign of it. So It shouldn't be lean. I always run PULP. I doubt it pings at high rpm, because the car doesn't ping at speeds over about 60kph, if I have had it ping for a second and I've held it at the higher revs it stops, its quite audible, and my motors not that loud. I just know that its the dizzy, as they have an aggresive advance curve standard, and the motor is worked, so it makes sense.
