how hard would it be to release the next revision with a can tune for the 91 octane gas users out west?

These tunes were designed to be compatible with 91 octane since its simple to add timing if you have better octane available...

so it's OK to use the standard 93 oct. tune with 91 fuel?

They aren't listed as 93 octane tunes are they?

My understanding was that the Diablo tunes for the SRT4s were 91 octane minimum.

your website promotes it as 91 and on the predator it says 93 i think let me go check. its just that everyone else is calling it 93 can tune.

I just got my predator last week, and it says 93.

Interesting....we'll have to get Brian's input on this.

i suggust that it should come with 2 can tunes one for 91 and one for 93.

mine says 93 octane also would be nice if it was 91

yes, the tune that comes on the predator is called the 93 octane performance tune.

DMW showed me his log file and show about 6* of knock retard and he had put in 5.5% more fuel. are you saying he should add more timing also?

but still it should come with both tunes that way the average user who know lil about tuning can just plug and play and go.

Yeah when I go into cali or az it would be nice to be able to flash it with 91.

Adding timing will increase the knock..

Mike was saying the tunes were designed for the 91 because you could add more timing for the 93 octane.

Yup 91 minimum... Some 91's are better than others though depending on where oyu're located.

So just to 'malice sure, it's ok to run 91 in it? You mention that some 91 are better than others. Which would you recommend?
