Yea, I specifically bought a good charger with 6/12/24 stepped options (trickle / fast), 15a in, 5-80ahr output, think it's enough, made in Germany. Who knows if the voltage is stable though, I didn't run it through a multimeter.

I was careful not to open the door, etc. Who knows. I'll try again at the weekend.

Regarding the dual/ram and rom, makes sense.
What are your thoughts to meth? Seen a few M5 F10 vids where the owners seem very happy with the setup.

Plenty of cars using meth in the N54 world but I personally wouldn't. Seems to be one of the major causes of blown engines through either loss of flow or uneven distribution between cylinders.

For me it would be a last resort for additional power. With ethanol not being easy to get hold of the only other choice for power is bigger turbos. I'd think you could top 600whp with some premium petrol.

From what I understand there's a lot of messing around with a meth injection setup. The install is a pain and the maintenance seems a ballache.

Yes it did seem somewhat risky, as you essentially run boost beyond what the petrol can sustain, then if the meth has issues you have a sudden onset of knock which I assume the Dme cannot dial back itself
