I just installed a new buscher streetcore and on my test drive I got up to ten psi then it would drop right off .my hallman controler is set to 10 psi and we double checked all piping conections . Any help would be great

 

You have to have a leak if the boost was going higher than that before. Where did you install the boost input to the manual controller after installing the intercooler and lower pipe kit?

 

I set the controller to ten psi when I put it in and it held fine unroll I put the intercooler in tonight

 

I had the controller on with my stock intercooler

 

The input line is on the upper intercooler pipe

 

You either have a leak in a coupling or the boost controller has a problem.

 

The easiest way to find the leak is to build a boost leak tester. It's very simple or you can purchase one from a vendor who makes one. I think STM sells one.

It's a coupler that matches your turbo inlet size and a pvc cap. You drill a hole into the pvc cap and use a push type valve stim. Once you get the tester made make sure the car is off, take off the intake and then pressurize the system. It will be very easy to listen to for a leak without the car running.

Good Luck!
