[QUOTE="CMP, post: 12371264, member: 141166"] Will the stock tune pull those numbers on 91 octane? I know the octane level in the fuel will not give you any more power as it is basically a detonation resistance number, but is the stock Shelby tune setup for 93 or is it 91? From the documentation Ford is saying 93 is the level of octane required to reach their advertised hp/tq numbers. If that is the case it seems to me that the stock Shelby tune is a "93 octane" tune in itself (stock)..with 91 acceptable, but not recommended for ultimate performance. [/QUOTE]
