92 Octane Needed After Using Programmer?

[89vette]

My H2 runs fine now on 87 Octane. I'm thinking of adding an exhaust, intake and a programmer for some more power. For some reason it seems my H2 dies when it shifts into second. Is this the torque management feature people speak of? Anyway, I'm not interested in doing any mods that will require 89 or 92 octane.

Thanks
