Has anyone here heard of this?

"The E38 ECU has been changed for the upcoming engine configurations from GM.
Could a tune fix this ? NO, Even when the sensitivity is decreased the ECU is so sensitive that the simple act of a human blowing into your air box with one breath can make a car die.
To make a Ram Air system function, you must over feed the motor at a rate greater than that generated by the vacuum from the motor itself. This is where you will hit trouble, We found the limit of what is possible and that is what is being designed into the system.

Vararam is claiming an untunable ECU in the newer version of the E38. Has anyone seen or dealt with this or even know what they are talking about?
Tuners?
Bill or Chris?
Anyone?
