BMW 420I GRAN COUPE CUSTOMPRO STAGE 1 ECU REMAP

BMW 420I Gran Coupe in for a CustomPro stage 1 remap. With this vehicle being an earlier model, it had the N20 engine rather than the B48 in the later models. As you can see from the graph below, this vehicle saw absolutely huge increases throughout the rev range, seeing gains starting from as early as 1,500rpm. The performance of this vehicle has been completely transformed now that it's on our software, while also producing a great power delivery too!

Before: 168hp/257nm

After: 250hp/424nm

Of course using PPE on the car and sticking to social distancing guidelines
