I want to hear from the crowd what they believe is the best idea -- I want to make 500-550whp on track days, but will be cruising around daily at 400~ish. Will this fuel system do or do I need to bump to 60lb injectors? I want to make sure before I sell off mine and look for 60's.

Fuel system consists of:
T-rex inline
Walbro GSS340 intank
42lb. injectors
Stock rails/lines w/ AFPR

I think I was making that type of power with 38's, 190, Cartech external, stock lines/rails, Kirban regulator and Cartech FMU. The fmu did push the fuel pressure on up there, and that may be the difference between my combo and others.

it is bad to run 1005 duty cycle on your injectors at any time, dcreases life span and can ultamatly ruin some more than just injectors...i also am highly AGAINST fmu`s...in my turbo fox ATM i am running around with around 500rwhp, and 72`s with max of 52% duty cycle....plus the way i see it is that why not go bigger the first time :)

I would say dump the T-Rex, and run a BAP.
