The only prop stalling I have run into with my five blade warp drive was when I was running 125 hp NOS jets and then it was only when trying to lift out of the water and the prop came out of stall at about 15 mph. All of that is something you would have to play with on your particular plane to know what to expect before actually needed it in a pinch. No I have only run it on a carb but all the systems that I have seen on injection systems have also run the wet system. I would suggest contacting NOS as they build the best systems and they could tell you if it would work but my thought is that the injectors may not be able to keep up with the extra fuel needed and that time lag would be to slow for the sensors and detonation could destroy the engine before it got the extra fuel there.
