2017 BMW M4 stage 1 ECU Calibration

Stock Power : 431bhp / 550nm

Actual power : 419bhp / 570nm

Stage 1 : 492bhp / 721nm

Absolutely gorgeous Sakhir Orange M4 made the short trip across from Isle of Wight for tuning on the dyno , only issue we had to combat was the car was running E10 fuel - no records were getting set with this one but still awesome gains with a drop of octane booster in.

Please please avoid turning up for tuning with E10 in your tank as it’s only going to reduce what we can do for you

Lovely car that saw some great power increases but not as aggressive as we’d normally go due to fuel .
