Performance: No
MPG: just a tad
Rough Idle: Still there
Misfires: Still there

The only thing i gained was peace of mind and unfortunately found a defect in the head that i am trying to get BMW to check out. Hopefully a new head is in order

I'm trying to open/close some of the valves using a remote starter switch. It has two alligator clips but I'm unsure where I connect the clips on the starter. Anyone aware of where to attach the clips?
