I am running Injector dynamics, In my option I would not scrimp on injectors. Injector malfunction at high boost would not be a good thing.

No the biggest problem with "cheap"or modified (drilled out) injectors is the lower flow
They tend not to be linier and usually do not flow the same for each injector
they say they are tested and flow the same but only at 100% duty... what about 40% where the ski is building good boost?
5-o and others sell junk like I described, if you get some questionable injectors spend the $25 for a good injector flow testing (IMO every new injector should be tested)
last every injector has differant dead time settings , every injector maker/rebuilder should give you a data sheet for the correct settings
and if your ecu is not adjustable some injectors may not be combatible with your ecu settings
testing with e-85 this winter I have found the max flow for my bosch racing 1150 injectors
fuel at 4 bar boost at 25psi 9000rpm is about 400hp so I looking to go bigger too
