Go to home depot and get the following parts:
-PVC pipe end
-coupler with 2 clamps
-JB quik (or regular JB weld but i prefer quik)
-tire valvestem (you can get this for free if you know of any tire places or friends with junk drawers. if not go to wallmart.)


Borrow someones drill and make a hole in the middle of the pipe end. JB weld in the valve stem. then clamp the pipe end to one end of the coupler. JB weld around the seal. After this dries take off your intake pipe attach your new "pressure tester" to your turbo. have a soap and water mix and spray ALL of your intercooler piping where there could be a leak. With the car off use an air compressor to charge the tester. Have someone watch your boost guage to make sure you dont go to high (i always test to about 5 psi higher than i run the car at. If you have a leak the guage will either not charge or will drop off. the leak SHOULD bubble from the soap and water mix. Im not saying that you DO have a leak but this way you could find out for sure.

I know that people are now thinking , "wow this freakin guy is an idiot with ghetto ideas" , but it will work and it's cheap. That would eliminate the possibility that you have a leak. Not to mention fixing boost leaks even if they are small will make your car faster.

Please no haters. it is ghetto but it works
