I was wanting to know if it was possible to flash a 04 truck pcm with the os off my 02 to get better resolution on my ve table for 3 bar map.

No, different pcms, not compatible.
Will a 02 pcm plug into the 04 harness
Still wouldnt work.
02 is a cable Throttle body, 04 is drive by wire.
Way too much different.
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.
My 02 2500 gmc 6.0 is drive by wire and none of the gauges have to work because the 04 stuff if trasfered to a 70 firebird
Are you not running the custom OS? It's better than trying to mickey mouse something together and hope it works. Or use an '02 harness and everything else.
I was going to use custom os but when I changed it and looked at the ve table stayed the same size I decided to go for the 411 for better resolution
If you guys thick it won't make a difference in tuning out I will give it a shot but the is 20 kpa gaps in the boosted region
Can you post a tune? The tables in the repository for both years look pretty close to each other. It's hard to tell without looking at yours.
I don't know how to upload tune to form
You can repin the 04 harness to work with 0411 computer. You will have to replace plastic green colored covers or grind tabs off to get into PCM. It will double size of ve table going this route.
