I'm ready to go out and tune my engine. It is has a M90 Eaton running 8psi on a stock 1UZFE with an aftermarket computer and is fitted to a boat. The motor is a 1991 model. Do I need to change sparkplugs? I remember hearing something about moving 1 heat range cooler for forced induction. Also I am using Avgas at times, so won't be using platinum tip plugs as lead wrecks them.
