First issue I see is your concern for emissions. To the best of my knowledge, there is not a single turbo kit out there (including ours) that would pass strict emissions or is CARB legal. Not only do you need to keep your OEM cats, but the tune will need to be set up correctly as well. I understand your issues with superchargers, but they will offer everything you are asking. All supercharger kits such as the Sprintex, Kraftwerks, Jackson Racing, Vortech will allow you to use your stock header and front pipe with the OEM cats, and most of those kits also offer a CARB legal tune as well.
As far as knowing a bad tune? Well there are a lot of variables, but the big ones are running too rich, or worse, too lean, poorly set up ignition timing that could cause detonation, starting and stalling issues, and the list goes on.
