Hi , I have upgrade my M2 with these parts VRSF :
* VRSF Charge Pipe
* VRSF Downpipe High Flow Catted 200 cell
* VRSF HD Intercooler 6.5'' Stepped Competition
* Spark Plug NGK 97506 Laser Iridium ( not gapped )
* K&N air filter in its original air box

I did several DataLogs with different weather conditions

Thank you to the MHD team for making me the most optimal mapping for my M2 with these VRSF parts

Kind Regards
Seb.
