S55 What's the process to obtain a S55 M4 GTS or better M4 GT4 virgin .bin file?

I am embarking on the journey of self-tuning my own M4 myself (I did something similar with my old N54 many years ago), so I am looking for the highest power factory tune bin file, M4 GTS or M4 GT4 (race car), and then I'll build my own tune upon it.

We did a similar thing in the N54 days, where we always started from the PPK (IJE0S) or 1M (IKM0S) bin files as the base map, and then we gradually built on it.

I have a base M4 with the base map 317kW / 425hp, and would much rather start with a GTS or GT4 (S55 powered race car) bin if possible, than to start from the base map.

I know I'll need to turn off the DME checks in the GTS/GT4 bin, otherwise the car will be stuck in limp mode after flashing, because my car isn't actually a GTS/GT4... etc.

Thanks in advance.

P.s. I already have MHD Super Licence, and I have been using the GTS map for a few months now, and I like it. But now that I installed downpipes, Wagner TMIC, Wagner radiator kit (the 2 heat exchangers at the front), Wagner chargepipes, I'd like to push the engine more in the mid-range and top-end. I don't like any of the OTS maps, I use my car for track mainly, and the OTS maps shove in a mountain of torque from very low rpm, and make it hard to precisely control the power on corner exit. I'd much rather precise throttle control, than sledgehammer low-end torque approach of OTS maps.

With the older cars you can generate bin files from the BMW 0pa and 0da files. If you can find those for the GTS and GT4 then I can merge them into a bin files for you.

The newer cars probably don't use the same file names anymore but I expect them to do something similar with Intel hex data files.
