the xc70/90 browns flow the same as standard turbo injectors but high impedance so suit 240s i ran them up to 15psi on a 13c turbo no issues and great AFRS
next up would be the 850/v70 orange/white injectors ive run them up to 16psi thru a 16t no issues and great AFRS
theres also the v70 blues , i think they flow slightly more then the orange/whites
then the green giants . they would be way too big for a standard sized maf and boost i run them at 18/19psi with a 3" maf and tuning chips to suit
if you wanted the browns pretty sure my mate still has some , he bought them then decided to buy some whites cause hes going 16t
