i recently sent my fuel injectors out to get flow tested and cleaned.
they were a pair of stock 550 turbo2 injectors and a pair of RC 800s.
they came back tested as

536, 550, 832, 888

is this 50cc difference to be concerned about?
these will go into a 87 turbo2 with no porting, stock ecu and upgraded turbo.

I am no injector expert but 832 vs 888 is a pretty significant difference. Most flow results I hear people are getting within about 5 of the rated flow rate. I would personally find myself some new injectors. That is will over 5% difference, and that will make tuning on big pain in the butt.

That's quite a bit, but it may not be as bad as it looks.
Hopefully you received pulsed flow readings with the injector service, take a look at them. Since they also are an indication of how the injector will operate in normal conditions. If they are quite a bit closer to each other then it is less of an issue, until the duty cycle gets higher.

Some shops (for some reason) don't give pulsed flow data. Without it, you could have a weak or broken spring and not know it . The car would run like crap.
