Dyno tune starting point for heads & cam LS1

[gto_in_nc]

Hoping for a little guidance:

I have an '04 GTO (think "Monaro" if you are on the other side of the globe) with an LS1 & T56. I have added Pacemaker tri-y's w/ cats, deleted the resonators and added an x-pipe to reduce crackle. I also have a K&N intake w/ cone filter. I have an LC-1 WBO2 and have been logging and tuning for months - plaing as much as anything but have dialed in using AutoVE and have tweaked the MAF calibration, etc.

OK, fast forward to the end of this month...

I have a set of Dart heads with my name on them, ported and heat-coated. 225cc intake, 80cc exhaust, 62cc chamber (flow numbers available if anyone's interested.) Going in with them is a cam, 224/228, 0.600"/0.598", 112* LSA.

The shop that will be doing the work is gonna put in on the dyno for a couple of hours after install. They are an HP Tuners shop but offered to allow me to use FlashScan instead. So, two basic questions!

First, what should my thoughts be in terms of process & procedure? What should I do to VE and main spark before starting AutoVE? (Is that even the logical starting point on a dyno???)

Second, is anyone sufficiently familiar with both HP Tuners & FlashScan to be able to give me a simple "cross-reference of important stuff" so when they say "adjust table XYZ123", I know what the heck they are talking about!

Any help would be GREATLY appreciated!
