added Larger Injectors, how to tune w/Jet DST or Tunercat

Ok so the car is getting larger injectors, 19lbs to 24lbs.
Where do I go to start my tuning in the Jet DST or Tunercat program?

I'm not familiar with those programs specifically but I think you might find that setting in the "constants" category. One to the left of where you are in the photo you posted.

Here is all of the constraints open

#1 rule. Don't make people have to guess on the vehicle year, type, engine...
Not all calibrations are the same.

Details on the injector brand and even part number would be helpful. And what fuel pressure the injectors are rated 24 lb at. Unless they are GM injectors that were used in a GM vehicle to copy all the injector data from, there are only a couple of brands that supply all the injector data needed. It appears you are using OBD2 software. The injector data will be found in the first pic you posted, not in the Constants.
