For sale is a Burger JB4 F-Series, Type B, Pneumatic Wastegate. This JB4 is set up for ISO. I purchased this from a fellow forum member but decided to go a different route, so I can't really comment on the driving experience. Comes with everything you see in the pictures (JB4, USB cord, OBDII connector) and is being sold as is. Enclosure is plastic, not aluminum.
Asking $360 shipped.

Important note: Update to the latest ISO software before driving the car. This will ensure proper functionality once installed. Here is the webpage:
