First decide what's more important to you: being able to go in pretty much anywhere, and have a shop be able to fine tune your car or doing it yourself for that matter... or not paying a lot of money now and only going to shops that have hondata eeprom burners when you change the makeup of your car. If you want that flexibility, its better to save up a couple of months and get what you really want. I was having the same debate a while back over the Hondata, AEM, or PowerFC. I ended up waiting a little longer and paying a little more for the AEM, because its what I really wanted all along... (and its cool to drive around with a laptop and a digital dashboard :thumbup: )
