Cobb data log and vacuum leak?
Is it possible to see if I have a vacuum leak with the Cobb tune? If I were to post my data log, can anyone help me to see if I have a possible vacuum leak? I will pay via paypal if anyone can help me.. thanks.

You can log and monitor boost/vac with the AP. You should be able to easily see via the monitor if you are not hitting target boost/vacuum numbers.
If you had a vacuum leak you should have a code, though (and/or you would probably be able to hear a loud hissing sound at idle). I had a very large vacuum leak in my E39 a couple years back. I heard it before I got a CEL. I used a mechanic's stethoscope to isolate the location. Turned out to be the rat's nest of vac lines under the intake manifold. In that case, the leak was so large that the car couldn't hold idle.
