Hyperspark Timing

[57s67]

I have a mild 350 in my 1967 Camaro.  The engine is fresh, 0.020 over, Lunati Voodoo cam 219* intake duration at 0.050 lift, headers, Pertronix ignitor and the Holley Stealth Terminator EFI system. 
I purchased the Hyperspark distributor, CD box, and coil and plan to install it soon. 

Base timing is currently at 9* BTDC and 32* total advance.  The install videos I have watched set the base timing for the Hyperspark at 15* and suggest 34* at WOT. 

Any thoughts on the 15* initial advance?
