My Wastegate is acting up, so I am trying to another Shop to see what they tell me and when I am driving back home, I lost all bost, Gauges doesnt go past 0 psi but I can hear Turbo spool but not like it has Much power. I did a quick check of the charger pipes and they are all intact, going to check Silicon Connects to see if one of them broke and came off. If it isnt that, what could it be??
Getting really upset with turbo now.

 

your I/C pipes may be in tact, but you might have blown one off and not really seen its loose. recheck them all! also, check your hoses coming from your turbo going into your wastegate. if you hear kind of a flutter noise when boost occurs then drops to 0psi, it may be your check valves gone to hell. other then that, it really sounds like a vacuum leak. also, where is your spring set at on your wastegate? what psi is the spring?

 

I can hear it Pull air from around the intercooler, I dont have check valves but a missing link, The wastegate is set at the stock 5.5 but I have problems with it, its not regulating and its flying past 6 psi like crazy.

 

If you don't see any vaccum leaks...Pull of the turbo and check for shaft wobble. I had a Turbonetics t3/t4 and it had so much wobble that the shaft would "stall" the wheel. In other words, the wheel would hit the housing, much like a starter does when it starts to go out.

 

Ok, I found what the problem was, The piping that goes from the intercooler to the Intake came loss. Thats good cause they told me if I didnt find the problem I would have to take out the turbo cause it was probably due for a rebuilt.
