FRPP Intake/tune and 87 octane

[01White5spd]

Can you run 87 octane with the FRPP intake/tune package? The website says 91 octane but I have read that the Bullit canrun on 87 and I thought it had the FRPP intake/tune.

If you're planning on using the FRPP intake/tune package you must use premium fuel (min 91 octane). The 2008 /09 Bullitt uses the FRPP intake but it features an adaptive spark ignition that can sense lower octane and retard timing to account for it. This feature was introduced in 2008 and your 2007 model doesn't have it.
