With 340 hp on tap thanks to its twin-turbocharged 3.0-litre six-cylinder engine, the BMW 1-Series M is an exceptional performance machine. Despite that, OK-Chiptuning recently got their hands on the car and have released their upgrade package for it.
For starters, the German tuner provides a bespoke ECU for the German sports car. When combined with an Evo 2 Performance intercooler from Wagner Tuning, custom downpipes and an Eisenmann racing exhaust, the OK-Chiptuning BMW 1-Series M delivers a very impressive 451 hp and 714 Nm of torque from 2500 to 4500 rpm. The top speed limiter found standard on the car has also been removed.
Elsewhere, this particular 1-Series M from the tuner includes a custom set of three-piece Schmidt wheels, coilover suspension, a rear spoiler and carbon fibre mirror caps.
