If so, then SI B24 02 12 dating back to March of this year is that document:

Attachment 353493

The issue then was EGS (transmission) and DME (motor) software calibration was "unfavorable".

Now it seems there may be another new SIB addressing it again.
So, what ThreeI wrote is absolutely correct.

The new SI B12 17 12 is again for "delay in engine response" with N52T / N55 Engine and 8HP45 Transmission to 03/31/12, and is a follow up to and replacement for the above SI B24 02 12, and the problem remains unfavorable EGS and DME software.

The fix then was ISTA/P 2.46.0 (or higher). Now it is ISTA/P 2.48.1 (or higher).

So, the "tip in" problem has now been documented, not once, but twice.
