Your car is in limp mode. What did you do to the car last, install a FMU? Whatever mod you just did put your car in kinda of a "safe mode". Its controlled by your ECU. You might be able to reset the ECU to get it back in normal mode, but the problem is likely to arise again. Need more information to accurately tell you whats happening.

The letters FMU stand for "Fuel Management Unit". Basically, an FMU is a fuel pressure regulator for turbo charged cars

fitting from the middle of the fmu connnected to the fuel return ?Fitting on the outer perimeter of the fmu connected to the the bottom of your stock regulator?
If so do you have an inline fuel pump?

Bro if you got hondata and 450's you better have a base map to idle them .Don't mix hondata and the fmu together.Either one or the other.
