Not trying to dissuade you Vince, but I can tell a couple of things from the pics of that car on the website. It is using 3-BAR MAP sensors where the factory used 2-BAR MAP sensors. This is a very common precursor to a performance (re-tune) upgrade. I would suspect that it is the GM Performance Division upgrade which I believe is CARB compliant. But you may want to validate what tune/modification has been used. Also, looks like the OEM air cleaner box is gone in favor of a cone-type air filter? Again, not a big deal but when smogging it in CA, you may want to get the OEM airbox. Most likely, not a very expensive item. Best case is that perhaps you can use these anomalies to negotiate price on
