Looking for opinions and help here. Starting on a project with an E38 controller and will see up to 10 PSI boost.
Vehicle is currently tuned with airflow only.
Have heard differing opinions about going airflow only or SD. For a street driver with A4 ......
What is the better method? Or something different?
I see there is a 2 bar custom OS available.
Thanks
It doesn't matter, you can tune with the the MAF/VVE or just the VVE (VE if you upgrade).
The E38 can support 2 or 3 bar without even upgrading to a 2 bar OS.
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.
What are the benefits to the custom 2 bar OS?

depending on how new the ECM is GM added some of these fixes to their own code. The main things are a real VE table, Boost Enrich and boost fuel cut option.
