which performance CAI tune to use?

[typan]

Here I Australia we have premium fuel 98, what’s the best performance CAI tune to use? Only can find Perf CAI 91 Oct in my Predator tool

[mikel]

there are 2 cai tunes, one says 91, the other does not, which is for our 93 octane, which is similar to your 98.

Thanks

Mikel to get this right, your saying if I use 98oct & fitted a CAI I should use CAI 93oct tune?
Options in tool are
Perf 93oct
Perf CAI 93oct
Perf 91oct
Perf CAI 91oct
