BMW 420i – Stage 1 Remap
This BMW 420i came in for an NVM stage 1 ECU mapping on the dyno. The N20 powered engines are de-tuned from factory, so the gains are very impressive.
On it’s stock run the N20 produced: 174 Bhp and 264 Nm.
After a couple hours of custom dyno tuning we managed to push: 246 Bhp and 405 Nm
