Water Meth system on W204 C63 2012 model
Hi guys
I currently have a w204 c63 2012 model, stage 2 software, no hardware upgrades. I’m looking into the water meth system, any advice and direction on where to start and how to start will be really appreciated. Do I need to do any conversions besides installing the meth system. Stay blessed.

water / meth is a two-part system to address two issues - knock and fuel. typically it is used when you can't get any more fuel into the car or you're wanting to get more power past the knock threshold of the motor. methanol is the fuel and how much you mix depends on how the car is tuned and how much more fuel the car needs past what the injectors and fuel pump can provide. water cools the intake charge and reduces the knock threshold of the motor so you can run more timing. I can see water being helpful to add more timing, but I doubt you need the extra fuel from meth. I suppose if you wanted to install a water meth system on a stage 2 car with no hardware upgrades, you would just need the hardware and a retune but I would expect the results to be minimal.
