The shortest path to accurately getting this engine to do what you want is to input the proper injector data. Can you get it to do close to what you want by guessing at the data, Sure, the proof is in your possession right now. The correct way is to input the proper data, if you can't do that, mostly every other part of the tune is a guess/trial and error scenario.
If you google cold start LS tuning you will find enough info. to get you started.
