Aaaaaaand, if you get your mods later, I believe you can get stock re-tunes for free.
Please correct me if I'm wrong.

In other words, this time you will strap onto a dyno and dyno tune your car. They do however, have different tunes depending on your mods that they can reflash your ECU to if you add other mods on later. They're still very good, but a dyno tune is always optimal.

Last time I got dyno tuned, they only had to make a slight adjustment to my tune as I was running a little lean under high loads. Otherwise, my stock tune was pretty right on the money.
