I think you may mean high impedence or sometimes referred to as high-z as low impedence injectors go up to at least 160 #/hr.

Try racetronix.

The best and highest flowing hi-z injector is our Siemens L107FM:
http://www.racetronix.com/L107FM.html
These injectors will delivery apx. 73lb/hr at LS1 fuel pressure of 58PSI.

RC does have a hi-z 75 but they are very sluggish in performance and pose some tuning issues. You can make some serious HP on the L107FM's and they are much faster and can be run at higher pressures than the RC 75's. If you do require more fuel than the L107FM's can deliver you should consider low-z injectors along with an injector driver box.

I have the RCEng 75# Hi-z injectors and have had no problems with tuning, idle or driveability. Plug, tune n' play.

We have some dealers which have had tuning issues with them. Obviously it depends on your application and what you may consider acceptable for drivability and idle A/F. There is no comparison between the L107FM and the RC75's.
We have some customers running a base pressure of 72.5PSI/500KPa with the L107's which nets a static flow of apx. 81lb/hr. Siemens tests L107 injectors to 87PSI/600KPa.

Given the price premium for the RC75's and what it costs for a low-z injector w/driver most opt for the latter. Yes, PnP is nice but there are some tradeoffs.

There are some new hi-tech hi-flow hi-z injectors under development right now but there are no scheduled release dates.

FAST distributes an array of re-boxed product which is no different from what is available on the market now. They carry injectors from Siemens, Bosch and Delphi.
