2017 BMW 420i Stage 1

Stock - 184bhp / 270nm

Actual - 183bhp / 312nm

Mapro tuned - 279bhp / 412nm

As tuning sessions go they don’t go much better , a stunning car , V Power fuel and Good knowledgeable owner .

We are no strangers to the B48 engine and come very highly recommended on the F56 platform so we knew if it was a healthy car it would make great gains - especially married to a 6 speed manual transmission

Sometimes these will take 4-5 mods and fight you and others will work first time - this was done in 2 with just a very minor tweak and the results speak for themselves .
