Thats strange.
Ive actually had people tell me to bump it up to 18*.

Would the timing really make it run lean like that though? It seems like its not getting enough fuel.

Probably by the stupid people that dont realize that higher timing only makes more power "to a certain point"
Just because the car isnt pinging, doesnt mean its right!
