OVERBOOST

[syclonekid43]

OK LASTNITE LEAVING A RED LIGHT I HEARD POP POSSIBLY IN THE INTAKE. TRUCK RUNS FINE BUT NOW ITS SHOWING 2O LBS OF BOOST AND NORMALLY IT WAS ALWAYS 10-13 LBS . ANY IDEAS?

first, no caps
second, check to see if the vaccum line came off the wastegate. there is a nipple on the wastegate that is attached to the turbo.

there are 2 lines on the turbo, one goes from teh compresser housing to the boost selinoid, the other goes from the boost selinoid to the wastegate.

both are important.

Do NOT run that much boost on pump gas, street setup, unless you know what you are doing.

If you do, you will BLOW UP THE MOTOR.

i unpluged the solenoid for now so i dont overboost it i checked all the vac lines they all look. ok theobijuan what do you mean no caps. im going to run it tonight with my scan tool with the solenoid unplugged. what should i look for on readings. i also noticed when im in to the gas you can here the motor ping a few times like your running shit gas. i alwasys run 93 in the sy i dont know what else to look for right now im lost on it

I hope you mean you unplugged the electrical connector...
Unhooking the vac line means just the opposite, full boost.

I would recommend staying WAY off the throttle if you are getting audible knock... VERY BAD!
