I just finished installing some Prosport guages I bought for my TII (Boost and Oil temp) Did a couple of 3rd gear pulls and my boost wouldn't go past 2-3psi. When it gets to about 0 I hear a loud sound like the blow off valve is open. If I remember correctly all I heard was turbine whine about a month ago. Also just so I know it is not the guage how high is the stock one supposed to go. The highest mine gets is about half way up the guage.. is this normal

You have a boost leak my friend.

Check all coupler connections, intercooler and manifolds for vac (or boost when its under pressure) leaks.

Problem fixed just had a loose clamp on the intercooler. Still only able to boost to 5 builds quick up to about 3 but then crawls to 5. Maybe a twin scroll problem or my guage needs to be calibrated to 0. was probably calibrated for sea level.

order of most likely cause:

1) boost leak
2) clogged cat(s)
3) effed up turbo
