Using an SCT X3?

Only reason I'm posting this here is because this section gets more views than the electric one. Besides, it pertains to my '01 Bullitt!

I just bought a brand new SCT X3 (note, X3, NOT SF3,) but it's completely blank. Now, obviously SCT provides some base "strategy tunes," should I use the 91 octane tune that's on it for now? Will I notice any change at all? I'm going to install my P1SC soon, and obviously I'd return it back to stock then. The only mods that are on my car that actually provide any kind of gains over a stock GT at this time are a Bassani catted X-pipe and of course the Bullitt intake.

You can go with whatever settings you want, as long as you pick the important ones correctly (gear ratio, rear o2 on or off) If you are putting 91 in, go with the 91 option. You shouldn't hurt anything by choosing something else. I have mine set with the timing set as far as it allows, its lean some, and I have it set for the highest fuel option (forgot what it was) and have not had problems. I cant honestly say I notice any difference between settings, or even with or without the sct tune.
