Iím definitely no expert here but just a few pointers enable 6cylinder timing. Iíd check for a boost leak too. You donít get close to target boost till around 3500rpm

Hello , thanks for the reply , how do i enable clylinder 6 timing also , i think the spooling issue is due to my wasgate rattle fix . I have set very low to avoid having all that rattle.But i will for sure check for vacuum leaks . Thank you

Enable 6cyl timing- it’s under user adjustments

What fuel?

Your throwing safety 2 - afr lean

Your LPFP is in the 50s already - likely will need to upgrade
