Enjoy increased power from your vehicle throughout the entire rev range on your BMW F20 F21 M140i.

Bluespark 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.
