Boost leak tester?

Son's 2005 srt4 is apparently losing a little boost at wot. Anybody know the best way to find the leak? Thanks.

Disconnect the charge pipe from tb and plug it with a tennis ball or pvc cap and coupler. Remove charge pipe at turbocharger cold side. Put another pvc cap in a silicone coupler fitted with an air hose fitting at the turbochargers compressor wheel. Set the pressure to target psi and run the compressor.
It'll isolate and test the intercooler system.

Spray the whole engine with super soapy water, look for a big bubble

Thanks guys, good stuff. I will try Duke's method first cuz I'm lazy, then Beigg's If I have to

Bike inner tubes work well for testing too

In place of the tennis ball or PVC cap?

Yes cut it the you can put one end on each side and the valve will hold pressure
