So meetup with the OP today and installed the JB+ on my 330 xdrive M-Sport. I intentionally dialed it to around the 2'O Clock position, as originally it was set to 3 o clock position.
Thoughts without JB+: -In Sport mode, when the car is initially accelerating from stand still and at low speed and rpm, the jerkiness is very apparent, in the lower gears. In Addition, it feels as soon as you let go of the accelerator pedal, the vehicle seems to immediately start to slowly engine break, slowing down the vehicle. Thoughts with JB+: -In Sport mode, when the car is initially accelerating from stand still the overall acceleration is slight immediate, but jerkiness is gone. Engine wise, I notice the slight bump in overall acceleration and hear more air moving. However, the vehicle doesn't appear to use the engine break to slow down the speed after releasing the accelerator pedal. (That is more of longer continuous coasting at the designated speed vs immediately start slowly engine break after releasing the accelerator pedal). Once you let go of the accelerator pedal, the vehicle still coasts at the higher speed and does not decelerate as much. Therefore if you want to slow down more immediately, you need to press down more and use of the brake pedal. The active sound is more apparent at higher RPMS and Speed than before JB+ Last edited by WXdrivefun; 08-03-2021 at 09:07 PM.. |

Has anyone used a boost gauge after they installed their JB+? I have the MX+ OBD Bluetooth adapter I tried using (it has a boost gauge in the app). Stock I was reading a steady 16psi (2022 330I). I installed the JB+ (3psi, 3pm position) and the boost gauge is reading as high as 23psi. The boost curve shows when I floor it that it hits 22-23psi for 1000rpm's and then drops down to a steady 18-19psi after that. The power feels great, no lag or sputtering or engine codes; I'm just very hesitant to keep the JB+ on when it's showing 7psi above my stock boost levels.

Im literally in the same position contemplating on putting a JB+ on my leased 21 330. Since its been a few years since this post, would you mind mentioning if you did end up going with the JB+, and how that experience was? Also, if there were any problems with servicing or returning the lease. Thanks

I don't know how I missed that post after yours and only saw yours and assumed that was the latest post. My bad!

I ended up buying the Dinan Sports tuner the other day, only because of the ability to switch modes via an app. Once again, thanks |

My impressions:
It feels like I have an "M335i" comparing it directly to an X2 M35i. It took around 5 minutes to install, however removing the clip can be an incredible pain in the ass if you don't have the right tool, the YouTube video made it look very easy unfortunately. For $250 shipped, it's by the far the most no-brainer mod you can get. Friend installed it in his Cooper S, and now his feels like a JCW. You really do feel like you have 300ish HP and 350 lb/ft of tq...running on 93 gas and Burger Tuning intake silencer delete which helps too. |

Nice! How far up (how many psi) do you have yours set at?

Does anyone have any information about installing a JB+ on a 320i/420i? The version I have only has a normal air cooled intercooler (no water cooled cooler). Would love some feedback if anyone has installed a JB+ on this engine!
