B20 123 Ignition Timing Curve and MAP Curve Suggestions

Getting help from 123Ignition is just bizarre. They include stock curves in their cheaper models but the Bluetooth is left without any curves at all.

Anyways, I'm green to programming a 123 ignition. Anybody willing to share some curve files or at least the basic data? Here's my specs:

Standard B20 block, D-cam, 2" exhaust, 4-2-1 manifold
B20B big valve head, ported, shaved to B20E spec
Lightened valvetrain, somewhere between 9.5:1 to 10.0:1 compression
M41 J-Type
