I eventually replaced that factory 79 Q-Jet with a used pre smog Q-Jet that a CF member gave me. All I did was set the idle mixture correctly and then set the timing up a few degrees... The car runs great.
I don't think you'll have any problems with the tune because of the exhaust change.

Quick follow up to this thread for anyone interested in a similar change of systems. Turns out that 1975-1976 cars with AIR do in fact have a bracket and hole for a pipe that connects the AIR pump to the front Y-pipe, rather than the exhaust manifold as in other years and applications. The picture in this link shows it: http://www.parts123.com/parts123/yb....Z5Z5Z50000050G
The dual exhaust kits sold by Corvette Central do not have this hole and bracket. Is there any way around this without dumping the AIR system (not going to do that)? If not, I will likely just stick with the stock 2-1-2 and replace my tired mufflers, and maybe have the exhaust shop swap in a test pipe in place of my cat.
Thanks.
