More Boost or More Timing Advance?

Sure does. More compression, less timing you can get away with on pump, but also consider more compression could mean less timing needed period...

edit: when i start throwing meth at it again ill probably end up with around 23-24 degrees of timing again...

I used to run 10.9 all day and never had any black smoke, maybe a very little. Thats weird.
