boost on my t3 int wastegate is only getting to 3 psi?? need help. i checked all my pipes from the comp housing to the intake mani and no leaks detected. i feel some out of the bov but when i give it gas it goes away..

 

i found a extra tapped hole in the compressor housing but not sure if that will filter that much boost

 

i think i have a shitty wastegate. i unpluged it and drove carefully and it got to 10 psi in notime

 

wait the copresser side tapped hole is open? Plug that bitch up

 

get your wastegate checked. my internal greddy wastegate took a dump on me.

 

its your internal wastegate.I bet the spring inside is worn out. Same thing happened to me on my t3. It was only boosting like 2-3, so im using a boost controller to regulate the boost. My internal waste spikes alot, so ill be converting to external soon.

 

my wastegate has an adjustment on the actuator im gonna try tightening and loosening it. but my gate ia prolly junk

 

yeah mine had adjustment threads on the shaft also. It helps a little, but not enough. good luck
