Starting turbo!

well, hypereutectic factory pistons, and Megasquirt? I think you'll be lucky to get thru the tuning phase without a piston reverting back to it's powdered form. You must be very careful to keep your fuel ang ignition settings conservative. Any detonation while tuning/setup can fracture those pistons. Once it's set, and survives things, keep timing down, and the mix on the rich side under any boost, and it should live.
