| Message | It is not a DD, so 95% of the time it is on 100 octane.  I have two ECU programs, so I'm currently set-up like this: 91 octane: 13psi, ECU program 1 (11.3-11.5 AFR, very conservative timing curve) 100 octane:  20psi, ECU program 1  C16 fuel:  24psi, ECU program 2 (11.8-12.0 AFR, very aggressive timing curve) SS
