Sounds like the SLR is getting into fourth gear. Doesnt the SLR run the same trans and rear gear as the SL55/65 cars? If that SLR is getting into fourth gear then they figured out how to program the trans.

He could also be short shifting 2nd or 3rd in manual mode. My car won't allow this, even with the Speedriven TCU. Manual is not manual in the SL600 TCU tune. You suggest want you want, but it ignores you.
Or he may have changed rolling diameter out back, which effectively changes gearing, without really changing gearing.

Im not thinking straight. He has to get into 4th due to the speed of the run. Sounds like he gets into 4th between 2 to 3 sec before the timing lights go off.
