Just catching up on this thread, and thought I'd repost a post I made on AZ regarding the AEM sensor referenced a couple of pages back.
For those who don't care about factory fit Summit Racing gas an AEM 5 bar sensor for $63.
If you go with that AEM style sensor, I recommend the stainless one over the brass one (though it is twice the cost), as it's got an accuracy of +/- 0.5% rather than +/- 3% for the brass.
http://www.aemelectronics.com/5-bar-75-psia-map-stainless-steel-sensor-kit-655Ultimate accuracy doesn't always matter, but when the scale is so large at 5bar (and people are likely to really only read up to less than 4 bar MAX on their S4), that added accuracy can add some meaningful resolution to the MAP readings. The stainless version's accuracy equates to +/- 0.36 psi, and the brass version equates to +/- 2.175 psi. A potential 4+ psi swing of inaccuracy is not insignificant when people are looking at values like 20 psi. If you decide to go that route, let me know and I can hook you up on price with that sensor with my business accounts (though it looks like you've already got your solution).
My PM box got one message, a very humble one from someone who in my opinion threw down more than others in direct relation to my personal car. I felt compelled to toss him some R&D funds.
Thanks for the money Jared

Real quick, who has what 2.7 boxes here so I know what other boxes to worry about making an xdf for?
I know M Box... I also have G Box pretty much done.
Should I do A box as well?
I agree with the above, there's no point in worrying about any additional North American xdf's other than the M-box.
So what is the most common Euro 2.7 Box?
As for the euro boxes, my vote (as usual
) goes for the K-box.
