I have 87, 91, and diablo tunes on the inTune DCX for Jeep Grand Cherokee HEMI 5.7L
is the diablo is for 89?

Thanks

Diablo Tune is for 93 octane gas...

"Diablo Tune" is always for the highest octane...

if you only had 87 and Diablo Tune. then Diablo Tune would be for 91 octane...

but since you have an 87, 91, and Diablo Tune, then the Diablo Tune is for 93 octane gas...
