Thanks for finding out about the sensors, that really gives us a lot of freedom you know. I was looking at the places that the stock air box is held to the turbo and it may be hard to find mounting points for separate pipes. I will see what the filters directly on the turbos will do and if it doesn't work out I can take them back as long as I order them from Advance Auto Parts. They are the only ones that will let you order a special item and return it for no extra cost. Atleast not for me.

The problem with adding higher flowing intakes to the stock 600 is stock software.
It is programmed for a particular airflow. So it will allow more power for several WOT runs and than will trim boost back to preprogrammed parameters.
It drove me crazy when I was working on the intakes, until we did the software.

Could you not control this by vacuum or giving the sensors a constant value as not to let the computer trim back on the boost. The computer would only be controlling the waste gate to stop building boost, no?

After closer inspection of the diagrams this does answer most of my questions, again thanks it saved me a lot of searching.
Would you have the key to deciphering the numbers/symbols? I'm unsure of what some of them are in the EC diagram.
If you were to get the boost set to a level you wanted to be the computer would not cut fuel if it could not lower the boost right? I'm just putting my idea out there and let it be criticized before I get into playing with the vacuum lines and find out myself what will happen. An electronic boost controller would be ideal.
I know there are much easier ways of gaining power but I want to understand this myself and try to come up with different solutions.
Is this sensor in the picture the MAP sensor? Thanks, for your help.

thats the boost pressure sensor I believe. I broke off the part that the hose goes on when taking intercooler out and reconnected with super glue, still working. I think it tells comp that you are at top boost so it can limit boost thru wastgates.

That is the pressure sensor downstream of the intercooler.
There's also another sensor downstream of the throttle body along with a temperature sensor. Those operate together to replicate a MAF.

Are there only 2 pressure sensors besides two on each airbox?
The reason I ask is that in Mexico City the SRT-4's were achieving higher boost because of the altitude (7000ft. I think) Thus the car had to compensate for the lower atmosphere (less psi.) and had higher boost. My point is if you can get the car to think it is at a higher altitude the car would compensate for that automatically and you could get higher boost safer and theoretically much cheaper.

anybody do an oil catch can yet? 'just finished mine. It was difficult downsizing the hoses to fit the can fittings, but less oil going into intake is better for engine.

I thought about the downsizing issue as well. Do you have any photos of the project? I'm interested in seeing how it fit in there. I'm sure there won't be any issue once the stock airboxes are removed.
FYI: With the STAR tool you can advance the timing by selecting 93 octane instead of the California preset 91

With the SDS computer you can set the gasoline to "PREMIUM" or "LOWER OCTANE" which is designed for countries that do not have 93 or 91 octane gas.
There is no "CALIFORNIA" setting in the ECU...

After 3 hours in my 03 E500 going through the cars computer with Jonothon at Blue Ridge MB in Atlanta we came across the setting that clearly says 91, which is the highest that 95% of the gas stations in California offer. There was also a choice of 93. Thus i used the term California setting to refer to the preset of 91 that was chosen in my E500. I can't say that I have seen it in the S600 yet but I assume that it would be much the same.
