M54 is 2 bar. M20 is apparently 1.4 bar. GAS is 1.2.

For some reason I thought the E46 cap was 1.4bar but I just looked in the Bentley manual and it is 2bar.
That's a huge difference. In addition to the points I brought up in the other thread, you are drastically lowering the boiling point of the coolant. Liquids boil when their vapor pressure exceeds the atmospheric pressure. This is why water under a vacuum will boil at room temperature. Conversely, the boiling temperature will increase if you put it under pressure. I don't know what the vapor pressure of the water mixed with coolant is so I'll just have to use plain water as an example.
1bar - 212F --> typical atmospheric pressure at sea level
2bar - 248F --> pressure under OEM cap
1.2bar - 220F --> pressure under G.A.S. cap

Tempting, my DISA failed at 75 or 80k, I'm closing in on 130k now.
