my car spec as follows spool up wasn't too bad for the size of turbo full boost 1.8bar around 4000-4500rpm all way to red line 1 bar around 3500rpm but i changed headers for unequal (wanted the burble back) and not had a map adjust which made it a little worse but was told with a map adjust it would be fine.
