I have a 07 Auto TL-S with 31k miles. It has an ATLP J-Pipe, UR Underdrive pulley and AEM CAI w/ TB coolant bypass.

I was toying around with sport shift last night around 70mph in 3rd gear and I floor it. I noticed that when the RPMs get to 5200, there is a slight hesition. If I leave it in full auto, there is no hesitation at 5200rpm and flys right pass it.

I searched and found these threads, including the one with the video. It happens to the RL guys quite often, but I can't seem to find an explaination or fix:

Here is the link to the video, it belongs to static808, but it shows the same thing except:

1. My car happens at a little earlier rpm
2. My RPMs don't drop a little like the video, they stay at the hesistating RPM
3. The hesitation is half a second less than the video

For anyone who wants to try this:

Go 70mph (On a closed road! I'm not responsible for anything happening)
Switch to Sport Shift
Change to 3rd gear
Floor It and watch the tach after 5000rpm
