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 serious, reliable performance from your 2019 onwards Aston Martin Vantage with the JB4 plug and play performance tuner from Nforcd. This advanced piggyback ECU upgrade delivers factory-smooth gains of up to +100 whp and +100 wtq on a stock car, without opening or flashing the ECU. Installation or removal takes under an hour, making it a superb remap alternative that blends speed, safety and flexibility.

  • Power gains of up to +100 whp and +100 wtq on a stock vehicle
  • Quick plug and play fitment in under an hour, no ECU flash required and compatible with locked ECUs
  • Integrated CANbus and fuel control for safe, consistent power and smooth OEM-like drivability
  • Preloaded with up to eight maps for pump fuel, E85 blends, race fuel and WMI, plus a reduced-power VALET map
  • Optional JB4PRO Bluetooth adapter and app for on-the-fly map switching, datalogging, firmware updates, 0-60 timers and reading or clearing fault codes
  • User-adjustable boost by gear to improve traction from launch; not VIN-locked so it can be moved to another vehicle or resold

With full CANbus OBDII integration, the JB4 monitors and adjusts key parameters in real time, offering more functionality, safety and performance than basic chip tunes. Using the JB4PRO app you can view and record up to 40 engine parameters live and tailor settings to suit your fuel quality and supporting modifications. Fuel economy remains unchanged during normal driving, and the tuner works seamlessly with all factory driving modes.

Housed in a rugged billet aluminium enclosure and made in the USA, the JB4 includes a 5 year warranty. For performance gains, 91 octane fuel or better is required.
