It’s normal, mine does it too, as did my last one. 
It only does it when the heater fan is on so, it must be to do with trying to keep the coolant heating up as putting the heater fan on does the same as the radiator fan, i.e. it cools the engine.

well maybe the fan is on heat to keep me warm but the car is alos at operating temp as its in the middle thats as high as it goes but still the car revs up to  1200rpm i kina hate that sure those 2.0 s4s 1adftv engine be good enough that the car needs to sit reving at that while the heat is on or not . do you guys think i could change this in techstream to just tick  over at the 800rpm and instead of reving  its head of itself when  ever it fancies

This it perfectly normal.  The car does this to heat up the engine quicker on cold days.

As above, it's normal when cold rpm, is set high to heat the engine and get the cat/dpf up to temp also the higher electrical load also increases RPM

you can it no way change the rpm it's part of the ECU map what has a set strategy for a said condition

eg. A/C or high electrical load it will increase the rpm to compensate

tbh im not even sure using those additives are safe for the engine and injectors or they would put it in diesel before shipping it to stations

If k&n filters are good why toyota don't put it ?!

If wax on paint is good why toyota doesnt say anything to use it on the paint. 

If they use trash junk Speakers why they dont put good ones like focal jbl or so ... then you dont need to change them by yourself insted of suffer every drive ...

Why toyota dont add material that low the road noise then i dont need to deal with all the car parts that make noise ...

A lot if why Q.

Toyota and Lexus has a well deserved reputation for producing reliable (albeit unexciting) cars and commercials.  I trust that when it comes to reliability, that they know better than enthusiastic amateurs and that they see through hyperbolae and marketing.

I don't believe that K&N filters are beneficial.  Better airflow can only improve output on engines which can use the extra air flow.

Ch4.1 of my manual - Maintenance and Care says to wax the paintwork when water no longer beads.

Speakers in mine are fine.  HiDef sound production in a metal box which is rolling along metallised roads, potentially through wind, rain and adjacent vehicles, windscreen wipers going, demister on sounds like a losing battle - noise cancelling headphones might work though.

Probably the quietest car I've had in the last 45 years, better than any of the VWs, Hyundais, Fords, Fiats, GM or Mazdas in my experience

Well tbh on my 2014 Toyota avensis I did the speaker upgrade and a class d amp .there is alot of different than the Speakers I took out and the new ones I put in it's a big difference .but other than that I didn't change anything else or add any of those additives etc
