Hey, I currently live in Fairbanks, Alaska and the MAX octane fuel available in all of Alaska is 90 octane. What parameters (how much) do I have to adjust?

Oh and the torque management reduction hasn't made it bad on ice and snow like you guys previously thought.

Use the 87 tune

That is what I have been using but, when it come summer I would like to have the best tune on there without paying someone to do a custom tune (just yet ). I have used the 90 octane with the 89tune but I was just wondering what parameters I can adjust on the 91 tune in order it to function well on the 90.

this is a 3.5?

if you have an 89 tune, there is little to nothing to gain trying to tune it for 90 octane

You may be able to add 1* of spark...

There not much to gain on the 3.5 at all. I have no idea how you guys saw any gains on it. I'm thinking this may be a 5.7 truck though. Not sure.

Oh, my bad. Yes, this is a 2012 5.7 Ram 1500

OK, so there is no 89 tune, you can either add some spark to the 87 tune, or pull some from the 91 tune, and monitor KR.

Huh, I could have sworn there was an 89 setting that I put it on. Oh well, how much timing do you think I will need to pull from the 91 tune?
