How can these variables ever be safely tuned out of what the (already sensitive) ECU wants to see?

If you want to continue to compare the two kits my next worry about the stillen kit would be the SC sitting so far away from engine, which seems similar to the previous vortech kits. That usually causes a lot of deflection in the bracket contributing to the belt slippage that everyone complains about. Hopefully they learned a lesson and added a way to stiffen that thing up a bit. Final concern with the stillen kit would be MAF location. i'm waiting to see where they actually put them, but i'm guessing they are going to have to share that main charge pipe. Not sure how the factory ECU is going to like that, or the fact that they are not reading a real intake air temp. Unless they add another IAT sensor post intercooler how will the tune know to change if the temp changes? I mean you can make the most efficient IC set up in the world, but it will change temps to some degree through the course of driving/racing etc, and the ECU should be able to see this to properly compensate.
