Plug in up to 35 extra wheel horsepower in seconds!
Finally our popular and well proven JB Plus quick install tuner is available for N20, N26, and N55 applications! Boost is user adjustable up to 4psi over stock providing gains up to 25 wheel horsepower and 35 wheel torque on the N20/N26 motor and up to 35 wheel horsepower and 45 wheel torque on the N55 motor. Timing and fueling remains managed seamlessly by the DME preserving all factory safety systems.
While the JB4 is the ultimate tuning tool the JB Plus is a quick and simple way to add a few HP with minimal cost and minimal install effort. Something that anyone can buy, install in under a minute, and really feel from the drivers seat. Compared to our Stage 1 tune it offers a lower cost and easier install but lacks the additional benefits of MAP sensor control and data logging. Depending on the settings and conditions expect a little less horsepower than the Stage 1 all else being equal.
Fuel economy during normal driving is unchanged. Compatible with both pneumatic and electronic wastegate vehicles and all driving modes. Automatically detects the engine type upon installation allowing the same unit to be used for any F series N20, N26, or N55 application! Not available for sale/use within California.
For those who want to start with the JB Plus and upgrade to the higher power more advanced JB4 tune we offer a 100% trade up credit. To qualify simply purchase the JB4 system from our website directly and then after receipt mail back the JB Plus along with its purchase receipt from BMS or any authorized reseller and we’ll issue a $199 refund against your JB4 purchase. Offer is valid up to one year after purchasing the JB Plus.
