Unlock precise boost control on your Kia Stinger, Genesis G70 or Infiniti Q50/Q60 VR30 with this pair of JB4 EWG add-on connectors. By enabling the JB4 to directly adjust electronic wastegate duty cycle, this plug-in upgrade adds valuable tuning flexibility. It is especially useful on modified cars that struggle to hit target boost, and can sharpen boost response, turbo spool, shifting performance and overall feel.
