We just finished testing our Z4 35i performance software. Along with improving performance we also configured it to work flawlessly with the DCT transmission. The software adds a significant amount of torque thru the midrange. The dyno below is our 14 PSI tune on 91 US 95 Ron fuel.
Feel free to PM or email me for more info or if you have questions
** Update**
Testing has finished on our end user flash loader that allows customers to install their own software without removing the ECU or installing hardware in the vehicle. Once installed the customer can switch between stock and tuned software maps with the push of a button.
