I have an 05 v6 mustang with duel exhuast and jlt series 3 intake. Im currently running the jlt firm shift canned tune becuase I like the firm shifting and it uses 93 octane gas which we have here in NY. Now there is also a jlt intake tune in there to but it only use 91 octane and doesnt have the firm shifting. Can I change either one of these to make sure im getting the most out of my setup and what changes if so.

You could try the non firm shift tune, sure.

Thats not what I meant. I know i can use the non firm shift tune but what im asking is what tune is best with jlt series 3 intake. The one that is on the intune now is only for 91 octane and i can get 93 here so what can i do to utilize the 93 octane.

either one is optimized for the CAI, you can add 2* to the 91 tune in the global spark parameter to make it a 93 tune.

Thanks

Thats what I was looking for, Thanks.
