Controversy- 255lph + Trex Or 255

Shoot, for 300rwhp you could get away with a standard motorsport 190lph. The GSS340 would be fine too, certainly won't hurt anything. I have an old Motorsport 255lph, and I had to add a T-Rex when I went from 100 to a 150 shot. The 255 could pump the volume but not maintain the pressure. I have to maintain almost 100 psi of fuel pressure, and the pressure would drop off without the T-Rex. Not sure if that is any help to anyone.
