burst dps	148120.002	142553.071	139769.614	134202.682
sustained dps	124831.447	120139.791	117793.971	113102.314

Why use Radiation for Grinneer instead of Corrosive ?
Why use Blast for Corpus Instead of Magnetic ?

The big dilemma is which status mod give more damage than Primed Heated Chamber ?
You can try to change by non-primed status mod but you loose at least 30 k burst damage for each ennemies.

Example :

For Grineer (replace primed heated change) :

Corrosive : Pathogen Rounds + Convulsion

Ennemies :      cloned          flesh           ferrite         alloy machinery
total damage	12681.945	17392.381	10294.756	12042.519

burst dps	118297.183	162236.130	96029.484	112332.617
variation       -29822,819	+23858,254	-105871	        -29822,82
sustained dps	99697.599	136728.130	80930.997	94670.828
variation       -25133,848	+20107,077	-89225,155	-25133,848

It's up to you.
