My vehicle is completely stock at the moment. What are your opinions on getting a stock 93 octane tune? Beneficial at all? Would it make a noticeable difference in power? Just curious. Thanks y'all!
The ramifications of a comprehensive answer to your great question are significant. The following is based on my experience in my car swapping parts in and out.
If you obtain an Accessport, you gain access to Cobb OTS tunes with it. 93 octane Stages 1, 2 and 3. The AP will log enough operating parameters for you to determine which of these fits your climate and elevation. At worst, you get a great boost in torque and better drivability for high performance opportunities.
Bone stock, you may able to use a Cobb S-3 tune which will in turn add 20+ hp. At most you will need a better I/C to use S-2 and 3 canned tunes. If you cannot interpret your logs well, get professional help.
Going further from orthodoxy, Razorlab reported some astonishing performance enhancements by running E-25 (93 octane plus 15% added ethanol). Check it out. I tend to trust his results having read a bunch of them over past 2 years and experimented with some of his ideas myself.
So at most you have invested in AP, I/C, and a professional tuner. $1500 max. And you should be making 220 whp on E25 and 200 on 93.
With $1500 and everything else stock, I could drive your car to within 5% of my best lap times at several tracks.
So all the other stuff you can buy is not about cost-effectiveness, its about fun. CBE for tunes, short shift for feel, etc.
