I half agree with you Joe.  I agree when you do something totally experimental that has never been done before, the testing you advise is prudent, especially if you are planning on selling this to the general public.  At some point tho', you either need to accept data at face value, or spend a fortune testing everything that you put on your car.  In my case the I installed the RS2 mods without ANY testing.  I could have installed $400 worth of sensors/guages and bought another $400 worth of software, but I bought an RS2 EM instead.  The baselines are dynographs from Audi on the stock car, and dynographs of an RS2 equipped car.  I choose to believe these dynographs.

At some point, you need to stop cutting bait and fish.
