Have a better idea, why don't you just send the injectors to ecmlink, they flow test them & give you all the data to input global, voltage correction & individual deadtime?
Side note, we sell IR guns at work & they likely won't work for what your trying to do.

You might be better off tuning injectors with an O2 sensor. Trying to tune a cylinder based on egt is risky, this would be safer and much more accurate http://carprogrammer.com/Z28/PCM/O2/IndividualCylinderFuelControlWithSwithingSensor1999-01-0546.pdf

I personally don't think it'll help where it matters.
At idle and cruise the ecu is going to change the air/fuel metering constantly in reference to the narrow band o2 reading, I guess you could modify the DA cells in those areas if the o2 sensor happens to be off a hair but I don't see the potential for much real world gains. It's a whole different ball game from carb tuning when you have an ecu measuring and changing things on the fly.
Where it matters most would be in WOT, when you're putting that trust into your wideband on being accurate, it would be nice to have a way to verify it is, but this is a point you wouldn't be able to monitor the site glass anyway.
It's a near product but I don't see a need for it in our application.
