VW Diesel Fiasco...

Why would a manufacturer possibly do that? In today's world of high horsepower car/SUV wars, what could possibly be the motivation to start low and add HP in 10k miles/km's? Mechanically speaking, nothing changes at 10k. Within 1k miles, the bearings and rings are settled, but that might give you 5 hp from reduced friction - maximum.

As for software, I assure you there is nothing that happens at some point in the future to give more HP. You could get your ECU flashed and a new/better tune could be installed, and that would make a difference.

Modern diesels are tuned to the max from day one. I have a 6.0L power stroke putting out close to 400hp and 750 lb ft of torque. That's huge and known to be tuned near 100% of it's potential from the factory. That's why so many fail - too many people push them over the limit with tunes and/or overheating. New 6.7L Powerstrokes are producing over 450 hp and over 850 lb ft of torque. In a pick up truck!

On the other hand, the US BMW diesel is de-tuned for our EPA emission laws and poor fuel quality. That's why I chipped it.
Any comments on how these tunes affect emissions as that is such a hot topic in recent days? I know this crowd probably doesn't put green at the top of the list or we would be driving Prius's but I hadn't seen any comments or data regarding emissions on these threads. Maybe some have experience with annual emissions testing for registration with/without chips installed?
