I know every setup like a different amount, but what are you guys running for timing in your boosted application, better yet, with a maggie? I am running about 19* WOT with 6psi with no meth. Just wondering where everyone else is at.

What's you compression set up at?
I run 19* on the street @ ~8.5#'s with stock 9.5:1 compression.
I can get her up to 25* with lots of 110 octane and no meth.
When I run nitrous, 20* (sometimes 22*) with lots of 110 octane and meth.

I am about 9.6-7 I think. My heads are milled .010 with stock dish pistons. What size pulley are you running dewy? My setup is kind of similar to yours, and yours def seems to run good! Your 19* on the street is with or without meth?

Mine's at 10:1, 9-1/2 psi, 93 octane. The most timing I can run is 15, 16, 17º at 4400, 5200, 6000 rpm.
Like you said yourself, every setup is different. And more and more often, I'm getting not 93 octane when I pay for it.
