I get 55+when driving motorway tree hugging 70-75. Even discounting for the remap you should get 50+
If the fuel goes into black smoke, and you have no DPF, then still it's difficult to see your own smoke. Can you ask someone to follow you and check?
Another one is the intercooler. Is it still ok or badly damaged? Leaking? If you have access to an OBD reader, i can check and let you know what i get on typical boost pressures
