Default Turbo loss HELP

I just took my car in for a compression test they said everything tested find but when I left I felt that there was hardly any power. Check the boost gage on my Cobb and I couldn't get more then 7.5 psi. I checked all the hoses and they weren't unhooked or anything. Before they checke it it was running great. Please help its an 03 wrx 1.0 with a newly built motor

take it back to whoever touched it last and have them show you what they touched. Really, a compression test is something you can/should be able to do on your own

I do know how to do it. It's just wanted to have another set of eyes on it. And have them go over everything to make sure it's good

Your pipe from the turbo to the intercooler probably is cracked near your hose clamp. After I went with an access port my car suddenly wouldn't hold boost. Turned out the plastic eom piece was cracked under the hose clamp.

check the plugs, possibly they were lazy and didn't torque and replace them properly and now are backing out

You should just go back to the place that touched your car like everyone stated and say hey my car didnt have this problem before you touched it why waste money for something they may have done.

Sounds like it could be a intercooler issue. Like stated above I would take it back to where you had the test done and have them look at it again. If you have lost trust in them check the following,

Y-pipe on the bottom of your IC
check the Y-pipe to turbo connection
check the IC to TB connection
make sure the intake is in correctly and all connections are tight
check all the spark plugs for correct TQ

^^^ is good advice. Take it back to the shop. If not, check what chris said. Also check to make sure the hoses running from your BCS are in place (not disconnected). I'm not sure what bcs you have, here is the OEM http://www.google.com/imgres?q=subar...r:17,s:0,i:123 do a google search for what you have.
