Hello all, was wondering how to swap my operating system from an 02 Z28 to a 01 express van? I have an 0411 pcm. I want to try the express van one with my lt1 24x conversion. Thank you much

Flash the computer with a GM tool and then license it.
If you try to do it with HP Tuners you are going to spends a few hundred dollars in credits again.
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.
Thank you, i know using the compare file didnt fix my issues. Just trying to dial in my tune for a while and cant seem to get anyone local to me to figure things out. I figure since the 01 express engine is close to the same as an lt1, i can get it to work better.
