The Mini Cooper Power Booster Kit is a 'plug-and-play' upgrade for instant performance improvement! This is a 'stealthy' upgrade with no external indication of the increased performance in your MINI. The only visible sign is the big GRIN on your face!  Easy to install and instant results.

The JB+ Tune Module can add as much as 20HP & 30 WTQ Torque, and the Sprint Booster eliminates the throttle delay common to the drive-by-wire electronic throttle bodies. The result?... Instant improvement with throttle response and MORE POWER!!

If your MINI has the 'Sport Mode' option, this kit will add another big step above Sport Mode engine performance.

Fits the following Cooper S models with the N18 Engine:

2011-2013 R56 MINI Cooper S Hardtop
2011-2014 R55 MINI Cooper S Clubman
2011-2015 R57 MINI Cooper S Convertible

2012-2015 R59 MINI Cooper S Roadster
2011-2016 R60 MINI Cooper S Countryman
2013-2016 R61 MINI Cooper S Paceman

Yes, this is not a cheap upgrade - BUT.... you can take the tradtional route and get a Cold Air Intake (about $300+) and an exhaust system (about $1000), and you won't see the gains this Power Booster kit will give you for less than HALF the cost! Take advantage of the hi-tech solution and improve performance the 'modern way'.

Mini Cooper JB+ Tune for more POWER to your N18 equipped Mini Cooper S! A simple plug-and-play device that adds up to 20 whp and 30wtq!!

Featuring quick plug and play installation the N18 JB+ adds up to 20whp and 30wtq to your N18 equipped MINI. Fuel economy is unchanged during normal driving and the tuning works in conjunction with the DME rather than against it ensuring optimal but more aggressive boost levels with air/fuel ratios and timing to match. Boost is increased 2-4psi on average depending on the climate and conditions. Unlike other N18 piggyback tuners this one actually works and completely transforms the driving experience. This is how the car should have come tuned from the factory. Will be fully upgradable to higher stages when released. Literally installs and removes in less than 20 seconds.

CARB Approved Under Executive Order (EO) No. D-744 for all 2011-2015 MINI Cooper S and MINI John Cooper Works models equipped with a 1.6L N18 turbocharged engine.

Installing a Sprint Booster in your car will:

  • Provide quicker acceleration 
  • Enable faster passing 
  • Increase the responsiveness when driving uphill. 
  • Allow quicker gear changes 
  • Provide easier rev matching

Sprint Booster V3 features:

  • 3 Acceleration modes (Off, Sport and Racing)
  • 36 Acceleration programs (18 manual & 18 automatic transmissions) 
  • Pedal lock mode 
  • Valet mode 
  • Ultra compact size / New Design 
  • Plug n Play installation

Additional MINI Sprint Booster V3 Features

Each mode (SPORT – RACE) comes with 9 steps-programs so the driver can choose the one that suits his driving style (18 programs for manual transmission & 18 programs for automatic transmission in total).  This allows the driver to fine-tune each mode (SPORT – RACE) according his needs by selecting one of the nine different programs on each mode. 

You can select 1-9 in SPORT mode (Green light) and 1-9 in RACE mode (Red light) with '1' being the least aggressive program and '9' the most aggressive one.  Each program adjusts the response by 3-6% so it can be fully adjustable and customized by each driver.

The Pedal Lock mode provides extra protection against unauthorized vehicle use. The driver can deactivate the acceleration ability of the vehicle when it's stationary through a 3 digit PIN. When Pedal lock is enabled the acceleration gets disabled and the vehicle stays on idle until you enter the correct PIN. 

The Valet mode limits the acceleration of the vehicle by 55 % - 65% - 75% and comes in 3 selectable levels.) It is activated/deactivated through a 3 digit PIN. By limiting the acceleration there will be a significant reduce in vehicle's performance (Power and Torque).

The compact size allows the driver to place the selector switch anywhere on the dashboard with the use of the double-sided tape.

MINI Sprint Booster V3 also offers the option to the driver to completely remove the switch from the device. In this case, the device will work with the last settings stored in memory. For example, if the driver disconnects the selector switch while in SPORT-5 (SPORT mode- Acceleration program 5), the device will keep as default the program SPORT-5.

MINI Sprint Booster Power Converters V3 comes with 3 Acceleration modes :

  • Off mode - Sprint Booster is deactivated. The response of the car has the factory settings. The LED of the Selector switch is OFF. 
  • Sport mode - Sprint Booster V3 provides improved response up to 30%. The LED of the selector switch in Sport mode is Green. 
  • Race mode - Sprint Booster V3 provides improved response up to 60%. The LED of the selector switch in Race mode is Red.

See the Sprint Booster Power Converter Version 3 Installation Instructions & Quick Start Guide.


If I already have a Borla sport exhaust and an AEM cold air intake, what kind of gain would I have. I am also installing a catless downpipe, cold side charge, and hot side charge.
The JB+ Tune Module can add as much as 20HP, the Sprint Booster does not add power, but eliminates the throttle delay.
