More parts for the GR. I installed the DTUK Stage 2 Race Edition box along with their pedal box and a DEFI boost gauge. Definitely can feel the power from the box and the throttle response from the Pedal Box is crazy. Needed the boost gauge because when using the DTUK the stock gauge will not read correctly. I like these parts because they are also controlled from a Bluetooth app and you can turn them off and run stock at anytime.
