So i'm running an 18g internally gated, last week my car started to only boost to 3psi instead of 10? Then after getting on it real hard it only went to 1psi? Then this morning it hit 10 for one run but after then it's back to only going to 3. What should i start checking to figure it out? Boost leak? BOV? wastegate? I'm not sure where to start my trouble shooting.

 

i'd start with a boost leak, then to the wastegate, then to the bov, but my money is on a boost leak.... pressurize the system and listen for leaks

 

Id start with checking for leaks,check wastegate actuator to make sure it isnt binding/working properly as well as look for leaks around manifold etc.Do you have a vacum pump?You can get one from a parts store etc and use it to test the actuator or even compressed air will work.

 

coupler ripped

 

Yeah i'm goig to rip it apart some time this week when the rain stops. I'll let you know the out come.

 

+1 or blown off

 

Not related to you but I bought a ssac wastegate supposed to be a 15psi spring, came with a ------- 7, checked my system many times but it only ripped to 7 psi, was sure it wasnt my spring so i spent all this time fixing clamps and couplers and ---- and I instally my MBC for ***** and ----, what do you no, instant 14psi

I then proceeded to blow many charge pipes, blew a sick one during tuning and thought I popped my motor. JKMotorsports zipties rigup to the rescue
