Hi guys when doing a late model e38 and a 2 bar sd tune do I write entire to the ecu as well as the fuel pump model or just do the ecu and leave the pump module? Cheers

Just the PCM needs a write entire if you are doing the 2 bar OS change.
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.
Cheers thanks
