NP guys, me, i just run 91 all the time...but totally your call, and understandable if you don't for day to day.
I'm ready for the 93 tune

Finally you'll love it.I have the 93 octane tune but with the price of gas I sometimes put 87 octane in it with no problems.You'll love the get up and go with the BB tune

I have no doubt I will love it and it only confirms my speculation when I read testimonials like this. Three days and counting.

Your Yukon will turn into a hot rod within minutes!!! 
bb tune with 87
What if you get the tune for 87 and then put in 93? Same thing is sences the change and does its thing. Are there any updates for the tune or once its tuned it stays forever? I know with some other tunes they have to be updated. JC. Thanks for any help with this.

then your wasting money. No need for better gas with an 87 tune.
no, if you get a 87 tune, then Justin will optimize everything for 87 octane.
you're better off getting the 93 tune and then if you want to run 87 every once in awhile, then you can.
Ok thanks for clearing that up for me. Just trying to weigh all my options with the bbtune. Sorry to hijack your thread. BTT.
