Car has 'crickets' and will be brought to dealership to address both that and the rear tap from the trunk
This problem has been occurring prior to both 'mods,' and I have removed them to test to see if the problem persists, and it does.
When driving in paddle mode, I find my car exhibits a strange RPM dip in 3/4/5 gear during acceleration. Example: Pull behind tractor trailer in 6th, slow down momentarily, check other lane, downshift once into fifth, then again into fourth, and proceed to accelerate into the next lane in order to overtake said truck. Whilst pulling through fourth, around 4k rpm, the car loses a noticeable amount of power, (Torque dip I presume) and the RPMs will drop anywhere from 200-500 rpms, then continue to climb as normal afterwards. This is noticed not only through watching the tachometer, but also the engine loses a noticeable amount of sound through this range.
This would also occur if I'm in slower traffic, shifting into 3rd to pass someone or pull into traffic etc.
Happens in 5th if I'm driving at a higher speed in sixth, and drop into fifth to pick up a couple MPH for whatever reason.
I attempted to take a crappy cell video of it today to show here, but traffic was s**t so I was unable to 'open her up'.
Was wondering if anyone had any idea what's going on here, also if I should bring it up when I go to have the TSB on the crickets taken care of.
Thanks ^_^

here's a tip
press down the gas pedal before you start shifting, or make sure the car is in gear fully before pressing the gas (give it about a second)
you can also double tap the shifter and it will skip a gear completely (fucking awesome in my book)
if you aren't on the gas the computer thinks you are cruising, then it will try to do the smoothest(slowest) shift it can to keep you happy
if you punch it mid shift, the transmission and engine wont have time to calculate and compensate for that change and lock up quick enough
cruising = slow shift = about 1 second to complete a shift and lock up(or even more time sometimes)
flooring it = very fast shift = around .1-.2 seconds a shift (sounds awesome with an exhaust!)
