I was curious as to which brand plug and type of ignitor i.e copper platinum ect.... and what type of gap. I am running a stock bottom end with garrett TD06 20g boosting to 12 psi controlled through a HKS evc2 controller. RC550 injectors and lexus afm. i know it calls for NGK platinum's from the factory. Pulled and old plugs which where auto lite platinum's which showed to be running what i consider to be extremely rich, and was having a misfire issue under load in 3rd gear (AT trans)
