This is the kind of tuning work we like: stock looks, massively powerful engine! That is what Mcchip-DKR has done to this BMW M6 Convertible, boosting the output of its 4.4 liter bi-turbo engine from 560 PS and 680 Nm to a huge 634 PS with 809 Nm of peak torque.
The power gain is great, but the absolute coolest thing about Mcchip BMW M6 upgrade kit is that the gain is achieved through software optimization only. With only 4 to 5 hours of work the technicians manage to extract an extra 74 horsepower out of the engine. That is cleanest, most affordable, and quickest way of unlocking a new level of performance from your Bimmer.
Not that the standard BMW M6 is a slouch – 560 is still a lot – but when you can have that much extra oomph in a few hours and at a reasonable cost, it’s an absolute no brainer, especially as the M6 is a bit of a heavyweight, and doubly so in the case of the convertible. The added power will definitely help with the acceleration and responsiveness.
