MCX guys, got this from Erik(MCX)

Hi Colyn.
It seems you already got the upgrade kit.
We sent out the very first kits with fuel pump.
We run 210 kPa total pressure on pump gas. This is 110 kPa(15.7psi) turbo pressure at sea level and about 133 kpa turbo pressure at 2300 meter, (this is about 19 PSI boost at 7500 feet in US units).
I shall test 230 kpa total pressure on pumpgas in the beginnig of January.
We have not tested the Powercommander with timing control yet on the Nytro, sorry.
Best regards Erik Marklund

just remember there pump gas is like 96-98oct.

Ya, but their 98 is the same actual octane rating as our 93, they use a different system of measuring their octane.

In most countries (including all of Europe and Australia) the "headline" octane rating, shown on the pump, is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, the octane rating shown in the United States is 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, is 91–92 in Europe. However most European pumps deliver 95 (RON) as "unleaded", equivalent to 90–91 US (R+M)/2, and some even deliver 98 (RON), 100 (RON), or 102 (RON).[2]

I read that
The USA uses PON and the rest of the world uses RON (different octane number values).

87 PON = 91 RON
91 PON = 95 RON
93 PON = 97 RON

YEP

Been running at those numbers most of the year.

And here I was calling you crazy to be running that. Had to hear it from the horses mouth I guess.
