You need to provide Injector mfg name, part number, where did you buy them from etc? Did you get data with these injectors?

Here is a great tool developed by Dave Steck (DSteck) on this forum to convert Ford injector data to GM. He used the Cobrajet 80 lb as one example which might be the 80-90lb units you are referring to above.

There are no part numbers on the injectors? Sometimes they are hard to see.

Data in Daves tool is good for your injectors. These will exhibit a bit of difficulty in idle. Will require some tweaking to get pulsewidth low enough. Try pulling 20% or so from Transient> Fuel min milligram

Injector data is not correct. Did you use the data under the sd80 tab?
