Pump maxed?

I'm sure the guys are on it, but I'll just chime in and say that I didn't have any problem at 420rwhp with a single GSS340.

I also did that with 30lb/hr injectors at 50psi base fuel pressure.
 
Not sure about the GSS340?But it is a wlboro pump. peace

Well there is 2 different models, it's kinda important which one you have.
If you didn't purposely buy the gss340, you probably don't have one, it's the kind of pump you have to go a little out of your way to get.
