I respectfully disagree a bit with the tune not being required for small mods. Half the fun of a tune is getting the most out of your mods, but also you correct for rich or lean which can be a bit dangerous for the motor. (Well lean anyway).

Also and perhaps more fun, our EDC can hold 5 tune "maps" (accessed using the Cruz control buttons)

Mine are
1 91 octane high alt map for denver
2 94 octane Cali map
3 2800 rpm valet map
4 kill switch (no fuel map)
5. Stock.

I use all these maps occasionally and they are worth the price of admission for a tune I would say. I'm up about 60 whp from stock using the z1 400 hp kit and Berk catback (that's based on increase from baselines before and after mods on a dyno jet). The stock tune did not keep up with my mods and I worry if I'd gone that route I'd be very lean driving around. (And would have to avoid wide open throttle)
