Are the performance/economy gains worth $549?
You get more HP's/less mpg savings with the higher 93 octane tune. I opted for the 87/89 tune bc I wanted more of an economy tune. I haven't had it long enough to see a difference in MPG's. I don't ever tow so I got my Tow/Haul button changed to "Sport Mode". So when it's in sport mode you can definitely tell there is faster/firmer shifting. All in all it was worth the 250 I spent.
