About the remap
Stage 1 chip tuning for the BMW 5 serie 525 TD 115hp increases power from 115 to 142 hp (+27 hp, +23%) and torque from 245 to 285 Nm. Turbocharged diesel engines offer the greatest chip tuning potential – optimizing boost pressure and injection maps delivers significant gains in both power and torque from low RPM.
Under normal driving conditions, chip tuning a turbocharged diesel can reduce fuel consumption – in Eco mode, savings reach up to 0.8 l/100 km thanks to more efficient turbo operation and optimized injection.
