Jack’s Explosive Hijack

Am I imagining things or is the explosive hijack card somehow linked to how much damage boom/dropshot scions or Salvo
DR-1’s deal?

Before I got the card to level 5 I never used to hijack scions because it would always take at least 2 hits to kill even a drone while also being super slow, salvos did ■■■■ all, now that it’s level 5 (not sure why I’m noticing at lvl5) I find myself oneshotting anything that’s not a boss/scion/DR1 and salvos actually making a good dent to enemy health

Is the card actually making any difference, has the hijack been stealth buffed, or am I completely imagining things and everything is exactly the same?

I think it is based on the Frag Grenade.
