    Very nice purchase!

    I didn’t even know this car existed. Looks like it’s faster than my Cobalt SS/TC.

    Only because of the weight, and Cadillac CTS-derived powertrain. It has the exact same engine, actually (Ecotec II – LNF).

    The same Stage 2 performance tune applies to both cars.

    Wait, so you’re saying that only 91 octane is required if you’re on the Stage 2 kit? I’ve been putting premium in my stock SS/TC. I live in NJ.

    Becuase 91 octane is the maximum octane in some states like California, GM designed the Stage 2 tune to support 91 Octane. You may get some engine ping at 91 octane however.

    I double checked with the technical docs, and it suggests “91+ Octane” – you probably are avoiding some ping, especially on very hot days, with 93. But for us in CA, it just isn’t an option. 91 is premium fuel out here. Mostly because of the California Air Resources Board (environmentalists), and their requirement for a perfume/special blend of fuel that is exclusive to California.

    I haven’t tuned mine yet, it has been in the shop quite a bit for post-sale repairs (thankfully all under warranty). This may be the worst-cared-for Hydro Blue in the 89 built – but I’m determined to clean her up.

    One station on my route has 100 octane, I may blend if I get ping.
