The 715 injectors are hi-impedance and have very different offset (dead) times. They will work but not correctly with the stock chip or any other aftermarket chip. I do have a solution that works properly with brand new Bosch OEM 759 (30 lb) injectors.

You certainly are free to try using the 715s but they will run lean at very low pulse widths because they need about 2X the offset (on time) than the original injectors. You may be able to hit the mixture setting at idle by adjusting the CO screw on the AFM but then you'll run rich at the higher loads.
