Yes, but in this case its timing related. I was trying to run a locked distributer using vacuum advance at idle retard enough to correct for the timing needed at WOT.
As of last night I've given up with that idea. I ordered an MSD boost retard control box. Supposedly it takes out 1, 2, or 3 degrees of timing per pound of boost made at the turn of a dial. It cost a pretty penny so I hope its worth it.
I was almost about to take the heads off and check which cylinders are pinging the hardest. I was under the impression that 1 & 3 were/are running harder than the rest due to the supercharger's location. I also wanted to maybe lower the compression some more. BUT I took a syringe and actually measured the dish of my new pistons. They are 18ml of dish; with a 4.120" X 0.040" HG, 64ml of head volume, and nominal deck to piston I should have about 9:1. Thats a lot lower than I was guessing at. Actually measuring things helps LOL
^^^ after that revelation I decided to buy a better ignition system; regardless of its astronomical cost.
Cost aside it is a really nice unit. It records boost pressures and timing maps. I might be able to get it to communicate with my LM-2 wide band system.
