60lb injectors @ 110% on a 370, pt88, it seems odd to me that at 11psi they at almost maxed out. no way im making 750rwhp at 11 psi. base pressure 60psi, boost referenced. -8 feed, twin walbros, aeromotive rails.

my 403ci with YSi/12.5lbs was maxed the 60lbers out at 108% and made 770rwhp. I also run boost ref with twin 255lph pumps and meth. My base fuel pressure is at 45psi.

Your base fp is higher than mine which should give you a bit more injector but you are still pushing them right now at your poiwer level. I would think your setup is probaly OK you just need some bigger injectors
Not every car is the same as you know and neither is each injector. Mine ar ethe Motron;s.
Take care

is that how you have your IFR table set up? with boost referenced return style fuel system i believe the flows should all be the same for each kpa label.

Yep.. Being boost referenced, the boost seen at the nozzle end of the injector puts the "delta P"[net psi] at what the base setting is...
IE:
Base. line off = 60psi.
Gauge reading w/ 1:1 ratio boost reference, @ 15# boost = 75psi.
Delta P = 75-15, right back at base of 60.[Thus, you are getting fuel volume at the 60psi pressure.]
