A tune is a reflash. And you don't need a boost controller. When you get a tune yor tuner will adjust your boost through the ecu.

The stock unit is incapable of consistently controlling higher levels of boost. Hence why you need a boost controller of some sort to help keep more control of that air. The tune is whats used to set the PSI.

You guys are correct, you dont need a boost controller but a 3 port is a good addition. Really alows the tuner to manage boost throughout the rpm range. In my case i found the boost to come on strong and hold to red line.
