You might want to check out the product review section.
Apparently there are some flash upgrades that can retain your original engine settings and can be reset by you before you take the car in for any servicing.
Some people will recommend a Cold Air Intake/CAI. I have my own thoughts about that stuff. My feeling is this. A CAI may increase your performance, but it isn't because it is making the air colder, it is more likely that it is just a freer flowing air filter element.
I haven't done any performance upgrades to my car, but the next thing on my list is a short shifter kit. That won't really improve your performance (except by shortening the distance/time between shifts), but it should tighten up the rather lose feel of the OEM shifter.
My buddy had an S2000 and now has a 350Z. I would like to try and get the shifter closer to either of those in feel.
Anyway, didn't really answer your question much, but stick around and keep reading. I am sure you will find so worthwile stuff.
Congratulations on your new car and drive safe.
