Am a new member to this forum so first and formost Hello (from the UK) to you all! I have an aspen silver 540i which has tinted windows, m5 front and rear bumpers, m5 wheels and the aluminium interior. Just to give you some idea of my vehicle.
Anyway am planning on carrying out some performance upgrades to the car am looking to increase BHP can anyone advise. I am definitely gonna get the ECU re mapped but have been told that that is probably the last item I should do as it is probably better to get the airflow (exhaust & induction) better before mapping ecu so that it includes thos particular mods.
Has anyone any experience of fitting an induction kit and also benefits??? Not sure wether to just replace the filter with a perf filter or to include full induction, has anyone heard of a gruppe m ram induction kit??
