Does your octane booster contain MMT?

From the Owners Manual, MMT is not recommended for our cars.

MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane number.
Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system
performance in some vehicles.
The manufacturer recommends
using gasolines without MMT. Since the MMT
content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer whether or not
his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformulated gasolines.

I would use the 91 tune with 91 octane gas.

no gas stations in my area have 93 oct so what should i do???
I live in California where the usual gas station only sells 91 octane.

But there are stations that sell racing fuels, like Torco, Union 76, and Sunoco.
During a 3 tank trial, I mixed 5 gallons of Torco 98 octane with about 11 gallons of Chevron 91 octane, which averages out to about 93 octane. I didn't notice any performance improvements with the Predator 93 tune vs. the 91 tune.
