Unlock effortless performance from your 2024+ Buick Envista 1.2L turbo three-cylinder with the JB4 plug and play performance tuner, supplied by Nforcd. This proven piggyback connects to accessible engine sensors and integrates via CANbus to optimise boost, timing and fueling for stronger mid-range punch and reduced turbo lag. Unlike a flash remap, the car remains unaware of the increased boost while fitted, and you can remove it at any time without leaving a footprint. On a stock vehicle, gains of up to 30 hp and 45 lb ft at the wheels are achievable.
- Up to 30 hp and 45 lb ft to the wheels on a stock Buick Envista 1.2L turbo
- Quick plug and play installation, not VIN locked and removable without a trace for an ideal ECU remap alternative
- Advanced CANbus OBDII integration uses live ECU data for real-time tuning and safety
- Multiple built-in maps for 91 and 93 octane, factory and Valet modes, E85 blends and unleaded race fuel, plus boost-by-gear for stronger launches
- Compatible with the JB4PRO app and optional Bluetooth 4.0 adapter to view and record up to 40 parameters, change maps, update firmware, and read or clear fault codes
- Runs smoothly with all driving modes and leaves fuel economy unchanged during normal driving, with a rugged billet aluminium enclosure. Designed and assembled in the USA with a 5-year manufacturer warranty
Helps improve 0-60 and quarter-mile times while retaining factory-like refinement.
