First they drove the car for about 50miles in 100% stock form and logged the data. They then installed our AIRAID cold air intake on it and went out drove it again for about 50 more miles all while trying to duplicate the bog issue using the test that user Jidonsu explained. We were unable to get our test vehicle to duplicate the bog in either form. We have been in touch with John @ Visconti and have offered to send him an intake for testing.
Testing Procedure:
Put car in 1st gear, let car accelerate to 5mph. Foot off gas pedal and let car settle around 5mph, which for me is around 800rpm or so. Quickly increase throttle. Observe whether the revs climb steadily and smoothly to 2000rpm and beyond or not.

Dave did you have a chance to review the graph I posted? It shows a very extreme case of the bogging (car actually slowed down under WOT). I can send you the log file as well.
I'm probably going to do a video showing the gauge cluster, with digital readouts of RPM, THROTTLE %, and MASS AIR FLOW RATE via the Torque app on my phone.
I can't do a log file at the same time, because Torque will be using the OBDII port for the video. Let me know if you'd like to see anything else.
Also, try higher gears like 2nd or 3rd. Doesn't have to start at 800 RPM, I usually experience it around 1500-2250.
EDIT: moved it to this thread, didn't see this post over here.
