Hey all, Im wondering if the stock ignition is hot enough for 12 psi boost. If not what is recommended to use. In addition what plugs to use. With my mustang I went to a colder copper nkg plug and gapped down to .025 Thanks for any suggestions

MSD BTM box set for your octane level, NGK4177 gapped 028 plugs and a good coil (there opinions on coils) should do it.
