Enjoy increased power from your vehicle throughout the entire rev range on your BMW E90 E91 E92 E93 325D wtih 197PS.

Blackbox design their maps to make power come in sooner, make great torque gains and hold them for as long as possible. Whilst we do make great peak power increases, for most vehicles this is not the primary focus of our tuning. We aim to get the best power possible across the whole rev range to make your vehicle perform best in real world driving conditions.

Our units considerably reduce turbo lag and will make your vehicle easier and more fun to drive.

Your vehicle should make very similar power and torque gains to those quoted, though small variances from vehicle to vehicle, and from dyno to dyno are to be expected.

"Before" figures quoted are based upon manufacturer's stated power output.


This is a Plug and Play unit, with photographic instructions provided for installation and adjustment. Installation and removal on the majority of cars is a breeze and can be completed in minutes.


  • Twin Channel - Controls Fuel and Boost Pressure in harmonyNear factory Air/Fuel Ratiosand EGTs are manitained throughout the rev range.
  • 5 User Selectable Power Curves to suit your requirements, ranging from economy mode to all out performance.


Boost & RPM Detection

Using our unique Boost Sense™ feature combined with Rev Sense™ RPM detection, fuelling accuracy is vastly improved over tuning boxes from other manufacturers.

This accuracy allows our units to make the maximum torque possible whilst remaining 100% DPF friendly. 


DPF Compatible

The Pro+Boost will provide your engine with the maximum level of torque whilst retaining clean emissions and therefore excellent DPF compatibility.


No Smoke

Conventional tuning modules without Boost Sense™ cannot accurately transition between off-boost and on-boost fuelling. This causes black smoke (particulates) to be created when the turbocharger is not producing boost.

Most tuning boxes either allow this to happen, clogging your DPF or reduce the level of fuelling which in turn means that the engine will not make the optimum level of torque.


Excellent Engine Reliability

The Pro+Boost’s Boost Control™ will alter the amount of turbocharger pressure available to the engine to keep AFR’s (air to fuel ratios) relatively consistent. This allows clean combustion; excellent torque and low exhaust gas temperatures (EGTs).

Maintaining low EGTs is useful when running a high level of tune particularly for vehicles that are under heavy loads such as those used for towing. This prevents components from overheating and causing reliability issues.


User Selectable Power Curves to suit your requirements,ranging from milder gains to all out performance.

Reprogrammable for future vehicles. No need to purchase multiple remaps or tuning modules, keep your Blackbox Diesel Turbo Tuning Module and send it in for reprogramming should you change vehicle in the future.

  • Increased Power - Eliminate turbo lag and enjoy smoother gear changes and boosted power throughout the entire rev range.

  • More Torque - Increased midrange torque gives faster in-gear acceleration and better towing performance.

  • Improved fuel economy - Increasing torque results in better average fuel economy.



For Diesel vehicles we expect to see improvements in fuel economy of around 10%. This means if you currently get 50 MPG you might expect to see somewhere around 55 MPG. This is very dependent upon your driving style. If you use the extra power and drive faster naturally the economy benefits will be lessened.


  • Twin Channel unit for Maximum Performance
  • Warranty Friendly Install (traceless once removed)
  • Huge Torque, Power and Economy Gains
  • DPF, ECU and EGR safe
