Oh.....there was also a leaf stuck in the left intake duct.

As stated in the other thread, it's not a lack of response. This car needs RPM's; that's understood. It's a weird jerk of power at ~3k RPM. There is almost zero response at the start, then at about 3k RPM, you get pinned back in your seat. It's not smooth at all. This doesn't happen to me until I've driven for about 20 mins. At first it's fine, it's a lot smoother. But it seems after I reach normal operating temp, it gets lagged.

I hear what you're saying. I had those symptoms as well. However, I haven't noticed them as much (or at all) as of 1.5 months ago after I switched to a better fuel (Sunoco). Also, it was noticeably much more responsive in lower RPMs after I cleaned the air filters. It could be a combination of both things....better fuel and intake air flow.

I think my next mod will be CAI......probably STILLEN's because of their filter placement. I don't want to risk sucking up water on rainy days, as it would be more prone with the Injens or AEMs.
