S4 Boost Pressure Test
Can anyone describe a manual boost pressure test I can perform to check the integrity of my hoses and connections? My S4 is loosing boost badly at WOT. Help!

you need to remove the airbox hose and plug it with something....
then pressurize the system and listen for leaks. AWE has instruction for their tester on their page. Instruction are pretty generic. The AWE tester has a fitting to connect to an air source....so you can pressurize the system through the plug. There is also another part to plag in teh S4 described and pictured in AWE's instructions.

Re: cool...good luck...I need to get motivated and do the same
Found leak...or should I say split throttle body. Looks just like the posts. Getting a new one to install tomorrow. Can't wait to have my boost back!
