Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Unlock responsive, reliable performance from your supercharged Audi 3.0 TFSI with the JB4 Group 12 plug and play tuner. This proven piggyback tuning box integrates with your factory ECU via CANbus to intelligently adjust boost, timing and fuelling for stronger acceleration and smoother power delivery. With power gains starting at 45 hp and 65 lb ft to the wheels on a stock vehicle, the JB4 is a superb remap alternative that retains factory safety systems and drivability.

  • Easy plug and play installation with full CANbus integration for advanced control
  • No ECU flash required and compatible with locked ECUs
  • Preloaded with up to 8 maps for different fuels and modification levels, including ethanol compatible mapping
  • Built-in safety strategies keep boost low until oil and coolant are up to temperature and reduce boost if the engine overheats, runs lean, knocks or overboosts
  • Wireless JB4PRO Bluetooth adapter support for on the fly map switching, data logging and firmware updates
  • View and record up to 40 engine parameters with the JB4PRO app, plus read and clear fault codes
  • Boost by gear control for 1st to 3rd gear via the JB4PRO app for improved traction and launches
