I'll take a look when I get home in a few dats.
What does the boost timing table look like...?
Are you getting any DTC's...?
Is your tune scaled for either IFR or MAF...?
it has a couple degrees boost retard setup to just be on the safe side,
no DTC
it is setup as SD, no MAF, with 60lb/hr injectors with factory non reference fuel pressure regulator,
When you exceed the ETC max airflow does the computer pull out timing before it goes into limp mode?
Found the problems BTM (B0401/B0402) was kicking in when going under boost and pulling timing and same with B6611/B6614
Now it holds timing under boost.Attachment 22900

Ok, I'm looking at your ctz file (saved in new format)... can you post a log when timing is reduced...
posted log file in first post, also posted log file after making changes on post 5
