The owner of this BMW 640d with the 3.0 twin turbo diesel engine producing 313 bhp as standard is a returning customer after the work we carried out with his BMW X5. After only a few days of ownership the car was in our possesion on the rolling road being tuned with our CustomPro software.
The 640d only comes in rear wheel drive, and as standard produced 474 ftlb with the owner saying it wasn't slow to begin with. Now with an impressive 334 ftlb with power holding on perfectly to the red line, this car drives brilliantly with another satisfied, returning customer.
Power gained: 54 bhp
Torque gained: 60 ftlb
