Fuel pump question

Hey guys , I dropped my tank to address a fuel leak & pulled the pump to see what it was . Previous owner wasn’t 100% sure
So it turns out to be a Holley gs344 with a Hotwire
From what I gather it’s a 190 lph
Anyone here running this pump ? Any good? Or should I change it with something else while I’m in there. .
So far I’ve got a good street set up with a
ta 49, head work , dutt neck, converter , ta downpipe etc .
Appreciate any input .

If it rated for 190lph, that is at 43 psig likely. As boost goes up, pump output goes down. A TA49 at 15 psi, probably Ok. A TA49 at max boost you are going to be borderline if not falling short.

Hmm , ok I’m currently at 16-17 psi so sounds like I’m “ok “ with that pump .
But I guess I should start thinking about replacing it when I want to turn it past 20?
Thanks for the info .
