Differences between Diablo tunes on Trinity for 2017 Durango

[17rango]

@ Diablo,
Finally got to load the Diablo 87 perf tune on my 2017 Durango RT and will be testing it now.

However id like a bit more details on the specific tunes on the tuner.

I see 87, 89 and 93 perf tunes.
Are there any differences between the tunes beside the slight increase in pwr/tq betwen the 3.
On a Durango its about 15 more hp and tq going from the 87 perf to perf 93.
Can you provide a bit more detail.

Also,
right between the 93 and 91 tune there is a mpg booster tune listed.
Is this tune providing any of the performance improvments of the other tune and whats the octane of gas required to run it ?

the difference is the amount of timing/spark advance.. more timing/spark advance for the higher octane gas used..

mpg booster tune is not a performance tune, just meant to try and get a little better mileage, made for 87/89 octane..
