As per Mission Performance, more like MISSION IMPOSSIBLE, Other than slow or no response at all, EXTREMELY poor Cust Serv. No business here

I communicate nearly daily with Alex @ Mission Performance. We text back and forth like a couple that just started dating...
That said he is in Russia right now, group tuning as far as I know, not that its anyones business, and he may not elect to answer calls and messages while abroad working. The me me me now now now mentality won't get you anywhere with any legitimate business. Shoot him an email and patiently await his reply. MP does not offer N63-non TU tuning anymore and honestly its an essentially non existent market not worth putting the R&D into. most of those engines are basically 2 strokes by now and adding power is the least of the concerns they have. |

Good to know and thanks for the info. As per MP, cust is always been poor. I’m new to the forum but not BMWs and most definitely not my first build. Cust Serv is not that complicated to rate, is either there or not.
Thanks again |

badblack550xi I just did my ARM downpipes and upgraded to Pure Stage 1 turbos with ARM cold air intake. I would like to use water/meth injection with 93... have you attempted this before and/or seen similar or better results than using 100 octane? I understand the risks when using water injection vs just running race fuel.
