I recent got the Predator. In Washington our premium is 92 octane which is smack dab in the middle of the 91 and 93 octane tunes. I do have CAI and exhaust. Isnt octane a mean number anyways so plus one should be ok right? I currently am using the 93 CAI tune...gimme your thoughts.

Suggest you use the 91 CAI or pull a bit of timing from the 93 CAI and try it to see which one you like!

Use 91. The SRT8s have a tendancy to knock, so using a higher octane tune, which incrases spark, is looking for trouble.

Thanks guys. I finally read the diablo website forums and all I have to do is decrease the timing by one degree from the 93 tune which makes it suitable for 92 octane....Stupid Hippie land and their 92 octane!

USNIS0922 how do you like the tuner overall??? I have the same car in WA also LOL have been thinking about getting one of these but never did!

Does it really help?

Ya it does. Update: I am using the 91 CAI tune now as I had a couple rough starts with the 92. Biggest change is the shifting/ Before it just shifted now when you shift you feel the force of it accelerating its pretty sweet.
