My conversation with an Edelbrock tech guy gave me the impression they've
put a lot of effort into making the system painless and into baseline tuning
it.  It seems to be meant for higher-revving, big cam small blocks, 
considering the HP rating and the fact that it uses a single plane manifold
instead of long tuned runners, like GM factory TPI.  Some but not all of
the low-RPM disadvantages of a single-plane manifold are alleviated with
fuel injection.  I would be glad to pay $2000 for the system, but the
tech guy said it will never be make for Pontiac motors (it's not even made
for Fords or for Chevy BB's) and they refuse to sell the parts individually
because of bad experiences with their older first-gen piece-together system.
Customers were (wrongly, IMO) complaining about mechanical specifics for
their particular applications, and their own misunderstanding of A/F basics
and tuning methods.  

Re: performance:  I'll bet it kicks ass.
Re: flexibility:  Don't you provide them with a description of your engine
mods, especially cam numbers, and they send you a PROM?  Plus I think it
has a narrower range of on-the-spot tuning with a little control box.
