GSR Technik 228i N20 ECU Flash Tune Now Available 50whp/90wtq

Greetings 2-Series Community!

Some of you may have seen the 2Addicts thread covering the development of our 228i into a Pirelli World Challenge TCA Class racecar. We have a great group of development partners and are excited to start offering new products based on all the development work we have done over the last year or so.

Check out the 228i thread:

We’d like to official announce the launch of a proper ECU flash tune for the 228i achieving approximately 50whp and 90wtq over stock. The dyno graph below is tune only on 91 octane – with listed modifications. This is an ECU flash tune (not piggyback) so it does require access to the ECU. Removal of the ECU is fairly simple – we should have a how to video up shortly. For those of you in Southern California – removal, flash and reinstallation of the ECU can be done at our shop in about 1-2 hours.
