I have the original Heico official Volvo approved tune from 2010 in my 2009 Volvo XC90 D5
All the documentation, graphs, brochures, and official data says wider torque curve, more power earlier on, but negligible fuel economy impact when driven normally.
One advantage is that it is fully compliant with local legislation and passes inspection at the 2 yearly technical vehicle inspection without issue.
