Well, I just did the update after work and it seems like that dead spot after taking off is smoothed out (the delay in throttle). My A/C always has been really good and it still didn't miss a beat so I'm not sure whether there is an improvement with that (maybe for some people who actually have problems with that?). It also feels like tip in/tip out low speed parking lot manoeuvres are smoother as well though I'm not a jerky driver to begin with.
My phone button, aux input button, and voice command button are now working again so it saved me from pulling my fuse. LOL.
As for Elizabeth, it doesn't burn tons of fuel on takeoff. LOL this isn't a JATO rocket strapped onto a C130 type update. Don't take such an extreme point of view to a simple thing! hahaha
