I doubt if that's your problem. Unless the boost gauge is showing to less boost, while the actual boost is still correct.
is the MIL on? Then get the codes read by a scanner.
Otherwise measure/read with a
scanner the actual turbo boost,
the boost control setting, the
pedal position and things like
that.
No the gauge is reading right and u can feel it in the car it's dead but still goes up the rev range ok
