Drove the car today. Running smooth and no smoke. Fuel pressure rail peaks at about 23000 psi..turbo peaking at 32 psi...

The dealer has flow tested the injectors before I bought the car..not sure if I can trust them or not..they also performed engine compression test. All seemed to be well

So if I am peaking at 23000 psi ..how could the pressure regulator at back of rail mis adjusted?

How can injectors be fried if car runs smooth and no smoke.


It seems like a software or sensor issue..but ..
