Diablo question

[white-lightn]

I see the different tunes for the diablo sport offered (87,91,93 octane.) I live in south GA and we don't have 91 octane around here. Just 87, 89, and 93. I dont' want to run 93 because of price. I run the 89 religiously because thats what my manual says? Will 91 tune work with our 89 gas?

I'll PM the gus from Diablo.

May as well save a few pennies and drop down to 87 and run the 87 tune...

I would not try the 91 tune with 89 octane, as this will likely lead to knock.

Thanks
