Are they getting that kind of power with an M6 or an A4?
My LS2 GTO made 452 with an MS3, FAST 90mm and 1-7/8" Kooks thru an M6.
An A4 would have been right around your goal of 425-430.

Facts:
LS2 intakes are not good performers.
Dual plane intakes are not good up top.
Cam is short on intake duration.

I have no experience with the MSD setup but anything that's "self tuning" raises my eyebrows as to it's ability to extract max hp out of your setup. I'd be curious as to the timing and fueling tables and how it reaches it's conclusions whereas the OEM stuff is tried, true and supports some BIG hp #'s.

Sorry but I just don't see you getting to your goal thru an auto with that combination of parts.
