My 42# injectors were maxed out at 10psi of boost. Base fuel pressure was 45psi and AFR's were around 11.5:1 ...42# ones are a waste of time to get I think.

I added the cost to build my entire drivetrane in my Nova...5.3L, cam, valve springs, intake, injectors, turbo and all parts for it, intercooler, HP Tuners, Wideband, rebuild my TH350, Fuel system, Coan rebuilt my converter, Pretty much everything except the rear end. around $5k. 3 years later still runs good, and there isnt a time I drive it that it isnt to the floor. Daily driven everywhere in the summer.
