Well I just spoke to someone at Katech and based on his calculations on a NA engine with 58psi fuel pressure they should max out around 650hp.
He said they are basically the same as the LS7 injectors.

i'm sure,,,, Katech made a mistake just like any campany can do ,but they are 38lb behind the supercharged Grand Prix and Regal 3.8 fuel system.

Also from a sponser on here FICINJECTORS said this about them bellow↓↓↓↓
