I swapped a 2005 truck with a 4.3 to a turbocharged 2006 5.3 with a 4l80e. After I changed operating systems for the 2 Bar my gauges are way off and most of the dash lights are on. Why would changing to a 2 BAR cause my gauges to be incorrect. I used the 5.3 PCM should I have used the 4.3 PCM or is this a different issue??
Any help would be great.
Thanks.

The 4.3 trucks were drive by cable and the 2006 computer you have is drive by wire. Maybe it has something to do with that?
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.
i don?t think so it was working fine until I swapped to the 2bar OS. I Thought about going back to the other OS but figured there?s no real point.
do you have the original file from before the 2 bar? open a compare? im new just throwing out an idea
Ya I tried doing that to no avail, i'm not really sure what the issue is. Appreciate the reply.
