I've tuned several Vortec heads with TBI conversions.
I like the TBI adapter plate pictured below!!!
The AE and PE needed for the Vortec heads is HUGE!!!
The factory Vortec timing tables are a good place to start.
15 lb TBI pressure regulator is a good idea.
Injector flow of about 70 lbs is about ideal!
Data logging is only way to know if the chip is working correctly.
