As Brian mentioned, the ultimate is a custom timing curve . I can't tell you how timing affects turbo spool-up, but advancing your timing does have a significant affect on low to mid range power. Just don't get carried away and have too much timing in place when on boost.

I run with 12 degrees advance (that's with the vacuum lines attached to the dizzy) and use a simple MSD boost timing retard module to progressively retard off the extra timing in response to boost as it builds. I do have better throttle response and more torque off-boost and don't seem to notice any negative impact on-boost, but that's all just seat of the pants dyno.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
