Drop in, tbe, NGK irridium plugs. Still black on the end of exhaust pipe. Best tune for almost all cars and bikes is just golden brown or just gray from my experience...I just try to keep the oil as cool as possible. Not sure if that works for turbos...sorry I'm old school, usually psynch carbs and such by ear and then check with gauges or electronics when the situation applies.

Seems like the drop in and the tbe brought it back to same mix as stock...but way more power.

Just wondering what all the options for AEM EMS are, guess I should just research thru AEM...thought hands on from guys cold help me decide if this is worth while...It may help motivate me to do more.
