You can adjust the settings to find out what works best for you. I haven't even tried the 93 octane setting yet( I should next week). I'm running strictly on the 87 tune and it made a huge difference in gas a performance. I'd say the only real settings you should change would maybe be shift firmness and maybe top speed limiter if you tires can handle it. Other than that I don't think you need to mess with it all that much. Now when and if you get bigger tires or new gears it will deff come in handy.
