How do you know when the boost sensor is gone?
because as soon as my car reaches boost the computer shuts down and pulsates but when I remove the sensor line while keeping the throttle above 2000 it will rev toward the redline or revlimiter easy.

what is the problem?

 

You need to be a little more specific. Does the car stop accelerating when you reach boost? Does it feel like a fuel cut? Have you done any work to the car recently? Will the car accelerate all the way to redline as long as you keep it out of boost? If your answers are yes, yes, yes, and yes, you are probably in the "limp home" mode. Pull the battery cables, depress the brake pedal for 30 seconds and then reconnect everything.

 

Yes to all Questions It feels exactly like fuel cut whe I reach boost pressure or a little over like 3psi sometimes.

I have tried resetting the computer many times, it will go away for a short time and come back.

 

Check your Spark Plugs, probably they need to be replaced

 

sounds like limp mode to me too. so after resetting the computer it works for a little while then starts acting up again?

 

This is very interesting. I have notice that my turbos primary turbo will not work most of the time. I notice that when it does work it works right after I start up the car, and then dies about 5 minutes later. Also when I reset the ecu it tends to work and then dies 5 min later. When it does work its a perfect boost pattern 10-8-10. Could this be it?

 

somone help please. Is my turbos in limp mode
