Hmmm.....I've wondered if the Shark would eliminate the dead spot at 4000, the one that requires BMW to ship your DME to Jersey for the fix. I didn't really notice it on mine when I got it but do feel it SOMETIMES lately. Living so far from a dealer makes it tough for me to do the factory fix.
If, like you guys are saying, it fixes that dead spot I just might have to get one.
The AA software would be nice too, may even be better than the Shark but again your sending your DME off to be programmed and it costs $200 more.
Thanks.....Barry
