Not saying these injectors won't work, just pointing out that you may get them to work correctly at idle a and part throttle loads (low-load) but they will likely cause lean conditions at hi-loads like WOT.

Good advice Sal, but after 10 years of dropping dozens of hi-impedance injectors in my Carrera, I have yet to run into any problems but good advice for any non factory modification to keep in mind.
Also, I might add, that I rarely drive my Carrera at wot since these multi hole injectors give me so much low end torque I rarely feel the need to go above 3500 rpm. Even at wot, as rare as that may be, I have not noticed any problems either.
Interesting to note that the biggest issue I had with high impedance injectors was that they tended to run too rich at high rpms and the major challenge I had was to adjust the air flow meter to lean it out. So lean at wot was never a problem.
