Mein Auto: 2009 BMW 535i Sport
Some Cobb experience

I've been running Cobb AccessPORT on my 535i Sport for a couple of weeks. Installed Stage 1 Sport Stock Throttle v401 about a week ago, and love it. It makes the car feel smooth as silk ... smooth acceleration and shifting. Even my wife loves it ... although she always is a bit nervous that I'm going to screw up our bimmer.

Today installed Stage 1 Aggressive Stock Throttle v401, and was taken aback by the extra power. Drove around for a while and decided to put it back to Stage 1 Sport, because it felt more "daily drivable", while Agressive didn't seem quite as smooth. Of course, when I'm in the mood I'll change it back to Aggressive.

Running 93 octane here, so even Drive and Sport modes kick butt ... while Agressive kicks a$$.

For the heck of it, I made some quick runs while monitoring the boost. They were run in regular automatic Drive, and all I did was hit the throttle to "passing gear" (as we used to call it). RPM went to about 6k each time. Boost for Stage 1 Drive maxed at 14.4 psi, while the Aggressive maxed an 17.1 psi. (That's another reason I went back to Sport. I felt that there's no need to work the turbo's too hard on a day-to-day basis ... just my feeling).
