Also, finished installing my sound-deadening. WOW, what a difference. First test drive, I can only liken it to how everything gets very quiet when your ears need to pop. Bass response from the speakers in the doors also greatly improved.

Replaced the noisy ~40mm fan in the Meanwell power supply with two silent 92mm fans:
Also, I averaged ~129mpg on the way back from the recycling center, where I was donating aluminum.
