I have a 05 lm7 that came without a computer so I bought one online. When I go to tune details it says hardware is P59 gm gen3 4.3 v6 but by vin its a 04 tahoe 5.3 8th vin in it is Z making it flex fuel 5.3 I believe. Do I need to just change all the injector data to match a lm7 or do I need to find a lm7 file and do a write entire maybe segment swapper or what would be best opition wasent planning on having to change any data just to get started start? I also have not licensed the pcm yet.

Just make it match the injector information from a non flex fuel vehicle. Find a stock 5.3 non flex fuel file from the repository and copy over that injector information.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
