Our power upgrades for the 2012-2013 F30 335i/335xi begin with a simple bolt-on tuning module that interfaces with the stock vehicle electronics to "trick" the computer into making more boost. By sending modified signals back to the engine computer, the Speed-Buster tricks the computer into safely raising the boost. And with careful programming of operational tables, the Power Module doesn't trigger torque limiters, monitors, or limp mode, which means safe power that won't kill your engine - or warranty!

Inside the Speed-Buster module is a sophisticated programming module, tuned specifically for the N55 engine on Speed-Buster's MAHA dyno. All development, tuning, and production are done in-house at their German facility. Speed-Buster's programming works seamlessly with the factory ECU to give an impressive increase in power with factory-levels of driveability and smoothness. All factory overboost protections remain in place and the system can be uninstalled at any time. A bypass plug is also included that allows stock operation without component removal if you want your BMW to appear stock. The Power Module works independently from the factory BMW ECU so it's unaffected by software updates and revisions, and all OBD diagnostics and service functions are untouched.

Installation is fast and easy - simply unplug the factory connectors for the designated sensors on the N55, plug into the Speed-Buster harness, and plug the Speed-Buster connector into the sensors. The harness uses factory-type connectors for a positive and weatherproof connection and an OEM appearance.

Speed-Buster is the premium German tuning module brand. All harnesses, modules, and circuit boards are premium quality, made in-house in the Speed-Buster facility in Germany. No need to pay hundreds of dollars more to buy this component elsewhere in a different box, or risk getting a lesser-quality part! We have researched extensively, and proudly sell the premium Speed-Buster product line.

Fitment note: this kit works on the 2012-2013 F30 335i/335xi with the pneumatic/vacuum turbo wastegate (PWG). From 2014-onwards BMW used an electronic wastegate (EWG) that restricts power gains. Technically this kit will fit a 2014+ 335i/435i but power gains will be limited. We have a workaround in the testing phase to use this kit on 2014+ models so check back again for more updates.


Next Upgrade: B1+, Intercooler and Chargepipe
To build a better turbo-powered BMW you must control the heat. Although our B2 kit only adds a Cold Air Intake, the best upgrade strategy is to upgrade the intercooler and factory chargepipe to avoid power-robbing heat soak and high intake air temps.
