I done a bit of research and standard injectors on the l61 z22se engine is 28 LB/hour
the LSJ SC injectors run at 34 LB/hour
in order for for the LSJ injectors to run without flooding the engine the fuel pressure needs to be dropped by way of the FPR mod on the standard 2.2 inlet manifold
tests have shown that a constant vacuum from inlet manifold reduces the pressure by around .8 Bar down to around 47 PSI
thus reducing the LSJ SC injectors down to 30.4 LB/hour from 34
to think 2 LB/ Hour will make a difference at idle is negligible but on full throttle is a different kettle of fish as the pressure will increase as a loss of vacuum inside the inlet manifold cos the throttle body opens up
just want to know i can install injectors before doing a remap
