If one opted for the hfs-2, what would be the cost to upgrade it to a hfs-3 later on?

Do you have a 53 or 56? For the 56 it will cut boost by interrupting the wastegate solenoid. For the 53 there aren't a lot of good options. We are testing a way to drop boost on the 53, the parts are here, we just haven't had time to get it on the car.

The cost to upgrade the 2 to the 3 is $250.
