Having my JB4 Stage 1 installed tomorrow while on the Dyno. Will do 2 baseline runs without it then followed by 2 runs with the JB4 Stage 1 installed. Expecting the numbers showed in the BMS site...
Dyno sheet will be posted up afterwards for the world to see. |

Dyno Results
Finally was able to get the car on the dyno this morning. The baseline was performed with the aFe Intake installed as I didn't want to waste time/money putting the stock on and off. The car delivered very well with just the intake alone. Looks like the torque numbers were higher than expected when compared to the another. My tuner said the 295.57 HP and 327.08 Torque is the highest stock numbers he has seen on his dyno for any stock N55 motor including a 1M that he dyno'd. That tells me we are getting a bit more power than BMW is letting on
With the JB4 Stage 1 installed we see gains in both HP and Torque, but to be honest not what I was expecting from the BMS suggested gains posted on the website. The best was 323.15 HP and 365.67 Torque. A peak gain of +27.58 HP and +38.55 Torque. That said, for less than $400 and two easy connections to insert it still is a good deal for this car. I hope the JB4 Stage 2 running Map 1 puts out better number with the added controls. |

Those are great gains for the Stage1! And down the road when you're ready for more power you can upgrade it to the JB4 Stage2.

how can you tell the difference between stage 1 and stage 2? is it the ability to change maps?
also i noticed the vehicle info on your site changed. when i purchased it, it was JB3B1 (Vehicle - 2012+ F30 335 (Harness B). are they the same thing? Product: N55 Stage1 / Stage2(JB4) Tune Options: Model Year/Build Date - February 2011+ (Harness B) RHD Harness - Don't Need RHD Harness Stage2 Addon - Include Stage2 USB Cable (N54/N55) - No USB Cable Vehicle - 2012+ F30 335 (Harness B) |

I installed the JB3 on my N54 and it was a bit of a bitch - I have heard the N55 is worse - what have been people's experiences so far?

When you order it does it come with instructions? Or do you have a link to your site?
