Granted JET Performance is a good company and all, but there are two major reasons why I would not even consider them.
1. Last time I saw a price for the Mazda 3 was on
http://www.sfxperformance.com/parts/JET65001.htm. They want almost $240.00 and you have to ship your ecu to them and be without a car for a week or two.
2. They flash your ecu for you and then that's it. If you want a different tune you have to send it in to them, be without your car for another week or two, and spend another $240.00.
To me, that sounds like it could get real expensive real quick. I'm just going to wait for the SCT V.2 Excalibrator, order it from Nikolas at Draxas performance, and then be able to download new tunes anytime that I want for my car and whatever performance parts I decide to throw on it. Nikolas made it clear in another post about this that if we ordered it from him he would be willing to send out the tunes for free in an e-mail so that we could download it onto a laptop and then into the Excalibrator. Now it may cost about $100.00 more initially but this definately sounds like the right way to go to me.
I also e-mailed Nikolas and asked about the Tuner and if he knew when it would be done. I'm waiting for his response and will let you all know as soon as I here from him.
