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.

No Engine light but serious misfires ending up in a bad end
I used this for a week, and it did give me at least 10% more power. But, after the 7 days, I start listening weird noises, and after another week I ended up at the dealer with serious issues with the engine. Dealer said to replace the engine. I have an N26 2013 BMW F30.

Bad experience
Does not work, ignited my check engine light and caused transmission and drive train malfunctions in my car. Seriously i regret purchasing this product.

Good bang for the buck
This takes like 5 minutes to install with nothing but a flat head screw driver at most.It’s not the same level of power as a true tune, but it does trick the ECU into safely adding a few extra pounds of boost that you can definitely feel at full throttle. It’s not some pedal commander that just gives you a ricer pedal, you actually get more boost throughout the whole RPM curve.If you open it up there is a dial you can adjust carefully on the circuit board to add more or less additional boost, basically modified the voltage off the MAP sensor in the charge pipe.30-40whp for $199 is a crazy deal. What’s even better is that I can trade this up for a full JB4 and just pay a few hundred for the upgrade and get my whole investment in this back. So it’s a perfect baby step towards some performance while working on building up towards more soon.

Best money ever spent for an extra 35hp
Super easy under the hood install and removal, on my 2015 BMW 535i. Instant HP I could feel, but I would recommended dialing it up to 4, as the stock setting is 3. Recently upgraded to JB4, but without other mods, the difference was minimal. I would definitely recommend JB+ for an average driver who is looking for a little more get up without any hassle.
