Misfire after MHD Tune
Just got 2-step Spark Plugs and coils, after putting just the stage 1 MHD Tune im getting a misfire code for cylinder 2 and 3, Switched the coils and checked the gap for the spark plugs, same thing, i was wondering if maybe the injectors are on their way out, any help?

You should be using OEM Bosch 3 pronged plugs at your power level, 1 step colder at most. |

Yep....1 step colder plugs is all you need, and gap them at .022".
