You can, to4r can make 430rwhp at 17psi. he just hasn't tunned it there yet. He did say that it was his first try. 
Also he is using a smaller a/r. Not the big 1.00

It depends on what conservative timing is to you.
Map Watch versus actual: there are factors that retard the timing. Your logs should show real close to actual unless you're someplace really cold or hot.
FWIW...nothing:
Always run race gas when playing with timing on the dyno. It's cheap insurance.
Since you have a hundred or samples at the current boost and timing (you do, right?) then why not tweak timing up a "small" amount. Since we don't know where you are at now, take that with a grain of salt. The timing might make some more torque up high, and maybe more than leaning out the mixture. How and when you make the change are important. Let's assume you advance after torque peak too. I always liked a flat toque curve with a really early peak.

I have a single turbo car here built and mapped by Rmagic with hks to4r 1.15 a/r
pfc. I will go on map watch tomorrow and see if that car is the same where map watch shows higher timing figures than the actual timing map.
I will take pics and post my ign map with comparison to a datalog of map watcher tomorrow also..

mmmmmm conservative timing to me is like a flat 11 deg advance on p18 row.

Is that 438rwhp on a dyno jet ? As I am told they always read higher ??
Is that with 0.84 a/r housing also ?? I know there is more power available but
but I don't see my setup hiting 438rwhp I wish thoguh lol.
Ok I will log everything and will post later.
cheers guy's.
