I wouldn't go so far as too say blindy. Just for comparison sakes it takes many tests before a theory becomes a law. Maybe under this one instance at near stock boost level the theory is true that a grainger works, but may not be true for all cases. Do you understand what I am getting at. It takes more than one case to prove any theory, and until the theory is proved to be reasonably true in all cases, is when I will accept it as the full truth.

What you are telling me is someone bled the boost 1psi over the max computer controlled boost setting. Its very viable that the computer allows this to pass as a margin of error.

So at the moment I believe DCX, for they designed the car, they know what its capable of. You have to realize I am not saying they are always correct, that would be blind faith, but what I am saying is currently they have the most knowledge of this engine and design. Consequently their statements hold more water for the time being.
