93 octane tune

[dyblega]

I have a 99 cobra and just installed the predator tune. It doesn't give me an option to install a 87, 91, or 93 octane tune. I was wondering if i did something wrong or if I needed an update. Is the predator tune 91 octane or 93 octane?

The predator tune should be for 93 octane, although after I got the fueling right on my GTO, I was good with that tune for 91 octane. You can always advance the timing and just keep an eye on the knock sensor to verify you're within safe limits.

The tool for the 99 cobra only has a 93 octane tune (Predator Tune).
