There's a bunch of us already running methanol injection on the S63, and even though I've been able to optimise my system using the biggest nozzles I'd recommend running, actual performance increase is negligible, with intake cleaning being the major benefit with this setup. Adding water increases octane, but also displaces oxygen-containing air, so there's always a balance to be struck. You can run added oxygenated fuels, but without specifically tuning for a precise known blend, you risk messing with stoiciometric ratios and leaning out.
Why not just throw in a wet NOS system, and cook your transmission (if the rods hold up).

Have to see how things go, I want to get on a dyno before doing this swap to get a good comparison of where things are at before and after
Currently running on map3 and the truck is brutal and that is 19 PSI, stock is designed for only 18, s63tu turbos are 22...
I'm not planning to break anything and want to maintain reliability
