COBB Tune - questions / reviews?

[TMLifer]

Has anyone tested dyno results comparing 87 octane to 93 octane on a stock tune?

There is another thread about the performance difference between 87 octane and 91 octane fuel.

People will argue you down and laugh at you for saying higher octane gives you the best HP. However, I have yet to meet a tuner who won’t tell you that the best performance comes with higher octane, but I had one who said theres negligible difference between 93 and 100 (race fuel).
