BMW 640D GC STAGE 1 CUSTOMPRO REMAP
Here we have a BMW 640D gran coupe that came in for our stage 1 CustomPro ecu software. It is common to see these cars not making what the factory claims on the stock software, however this is totally normal. We always see good figures on these engines that are on our software, and this one was no different. We saw horsepower and torque increases starting from just below 1,600rpm, which continued for the remainder of the rev range, while producing a power curve that replicated the original software, meaning that none of the drivability had been lost despite the huge power jump.
Of course using PPE on the car and sticking to social distancing guidelines
