I think they updated the part, plus they extended the warranty to 120k miles I believe. As for the AMG, I missed the power, but not the maintenance/repair costs. Hopefully the 335 doesn't turn into a money pit. The E55 with airmatic suspension might be in the cars a couple years from now.

The sport model N54's come standard with a transmission oil cooler, while not all of the non-sport model did. As a result, tuner's recommend non-sport cars get an oil cooler prior to increasing the boost. Mine's a sport, so hopefully I won't have any issues. Also, 1/4 and 1/2 mile creates far less heat that road racing.
In all fairness though, great 0-60 runs in this car doesn't mean squat in the 1/4. They are slow as hell, so I have no illusion of ever seeing better than maybe an 11.5 even with nitrous. Even that would be in perfect conditions. It's still fun nonetheless.
