Base Map for B20 Turbo

[Fakter1]

JDM B20 (higher compression w/ knock sensor)
Skunk 2 Intake Manifold & Throttle body (68mm)
550cc injectors
Stock Internals
T3/T4 turbonetics
.7 BAR wastegate (10ish lbs of boost)
3in exhaust & exhaust

Any ideas what base map to start with? Could I just start with the B20 stock and switch to "show boost maps"? I have VERY limited dyno time and somewhat limited funds for the runs, so any help would be appreciated.
Thanks in advance,
Carlos
