Remo,
Some say the 2.82 is only needed for top end, however I think MB would not put that in the CLk55 if it adversely effected bottom end to much.

The main reasons I want to run the 2.82 is because the C55 does and to keep CLk55 modules happy.

Other thoughts that make me want the 2.82 are the larger 4-finger prop shaft...I can only assume MB runs this for higher torque applications,why bother running it on the M113 5.4 if not matched to the torque of the engine? it also saves me swapping the trans output flange.

I will check again on the coding. Thanks for the heads up I will contact Beckman and find out what they know on ME2.0

Cheers
