Not an expert, but I seriously doubt it. In a perfectly functioning system, the SAIS only runs for 30seconds or so at cold start, then shuts off and won't run again until conditions (cold start temps) are met again. All the kit does is trick the SAIS control into thinking it's not a cold start during startup. Also, all other cold start fueling models seem to work fine as well. I definitely still get the high idle (1300-1400rpm) on cold start, that tails off as it warms up.
