Is it normal for the idle to drop when you turn the heater on ?
So something I've noticed with my evo 8 when at a stop if the heater is in my idle drops to just below 800 rpm and man does it shake like a **** what could be the cause of this while driving it's just fine just when I come to a stop it is blowing hot air so that's working but I can't figure out why the idle doesn't come back up to normal..
Maybe alternator or battery not sure which one it would be

PS I have torque solutions motor mounts on all 4 maybe that's it but if the idle would come back up to 900ish where it normally is it would not shake

Nope AC isn't on first thing I checked well at least I don't think it is my AC dash light doesn't light up when I click the button and I don't notice any difference if I click it or not

Light could be out. Check under the hood for a running compressor.
Anyway, if you have a tune, this is something that commonly gets messed up - engine rough or dying with A/C on.
