First Day back at work, and what an excellent way to start.
This lovely BWW M4 came in for stage 1 tuning which is now tuneable via OBD no longer requiring ECU removal.
GTS burbles requested also.
stock power 431bhp & 550nm
stage 1 510bhp & 680nm
gains of +79 +130nm which has literally transformed this M4!
The customer was extremely impressed at the difference, also surprised at the traction in the extremely wet conditions with over 500bhp on tap.
Instantly noticed the improved throttle response and instant pick up with no lag, not to mention the much stronger pull with all the extra torque.
