VGT (how to check if working?)

[hammerhead2]

How do you know if your vgt is functioning properly aside from bringing to the casa? I feel that there is a loss of power in my starex.

Boost gauge. But then, you have to know the values that it should put out at various RPMs and engine loads so that you can compare.

Maybe you just loaded a bad batch of diesel...
