I have noticed that bases don't count in the effect for tweaks. They are inputted into the systems but the only thing that is affected is range.
A base with an Volatile Projectile Overcharger will get the +100% range, but the base will not count that into effect of it's own range.
I had kits that has ~9.8k range with a laser, but when the Overchargers were used they still had ~9.8k range instead of maxed 10k range.

I also haven't noticed the + projectile speed doing anything on bases.

What does this mean.

What it means is, it will only shoot it's weapons at its range before the tweaks, but it will have the range with the tweaks.
Kit with a pulse gun that has 2.1k range will only shoot at 2.1k range, but the pulses will travel further than 2.1k.

Ok, I gotcha and I was already aware of this. There's a clever workaround that won't affect your DPS at all, though.

The problem isn't dps cause that works fine, its the range that is affected cause the base won't shoot at its real range.

Let me guess, you are testing this by marking enemies at certain ranges. I've gotten bases to shoot at their real range just fine. They won't initially pop the superitem and fire unless the target is in their vanilla range, but once they do get the tweak they'll use their range to the fullest extent.

Well, I did have 2 bases at pulsing range, pulled it back a few 100 distance, poped the tweak and it didn't shoot.

You mean you manually activated the superitem while it was equipped to the base? I'm not sure that works…

Well, the base can use it, or you can do it yourself. But regardless of base or owner, its range didn't improve, but when I put someone closer to the kit, it pulsed and the pulses went pass the other base. This test was done last uni and I will do another test tonight when I get home.

I confirmed through testing this uni that beams get the bonus range. I can't recall whether I tested projectiles but I suppose it's possible that the range aura is bugged for projectiles but not beams. But I'm a bit skeptical about your test results since you are claiming that the range aura doesn't work for either kind, which in the case of beams is contradicted by my own testing.

Well, I'm not 100% about beam weapons, but I know projectiles don't. With the beam test the overcharges might not have been poped on the base I was looking at cause it was during a BvB.
