Actually the SVT Programming can "self tune" so-to-speak between 87 to 93 octane. (00 SVT's especially well with the newer PCM & programming)

I myself could notice a difference between cheap 91 octane and the normal 92/93 octane Amoco I run.


...all I wish was 94 octane was available at the pump here... I sure could use it!!!


2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
