hi there,picked my new st-3 up on the weekend, even though im only 19 its the best car ive ever driven,love it too bits

it came with a bluefin unit and i have a scorpian exhaust on it, hopefully soon im going to put a large flow front pipe,cais and airtec intercooler and will be wanting phase 2 on my bluefin or 3 if needed, does any one know how to do this, im unsure if it will need to be sent away or not but it comes with a usb cable and connection on the back of the handheld controller. any advise and prices would be great
