Change the ETC Scalar to 7,300.0000 or higher. Add some air to your base running airflow, maybe 2.00 from 600rpm to 2500 rpm and see what that does. You may need to add some fuel as you are getting a lot more airflow.

Thanks man I appreciate any advice I can get right now I'll do that first thing and see what happens.

You will have to adjust your MAF and VE tables.

Does anyone know what fuel setting I need to change and to what, thanks

Not that simple. Read up and learn about MAF and VVE tuning. That is what is being referred to.

ECM 12940, 41, 42 all need to be fixed. You may not have them but can request HPT to add. They should have been in all e38s and e67s for the last year.
