Hi guys,

Just curious if my coil pack is stuffed up, it would be stuffed up in either high or low boost right?

took my baby 2 a dodgy place to tune, and they telling me that i cant hit high boost cause my coil pack is gone.

Could anyone confirm this for me... thanks.

forget boost its got nothing to do with it, its load that you need to think about. A coil can be stuffed and let the car idle fine and rev slowly. As soon as you get to high engine RPM situations or more so high engine load that is when a shot coil will break down and cause missfires and all that stuff. An auto elec can load test a coil for you and as more load is put on the coil the coils output will go all over the shot or there will be no output at all
