won't maintain boost.....

[jimmyp]

Did my wicked wheel this weekend and it seems like for one, my truck wont build much boost 20lbs in 80hp daily, and when it does it seems like it just falls off as soon as it gets there. It also has a low pitch hissing sound. Should I start looking for a leak at my intercooler boot?

Im gona see how it acts going home, I wasnt in conditions to be seeing how much boost I could make in traffic this morning.

my truck is doing the same thing. I don't have a ww but used to be able to get my truck into the 28-32lb range if i put it on extreme with my tony wildman chip. Only did that like twice, but now I can't get it over 20lbs, regardless of the chip setting and it surges from 15-20lbs. did you ever figure out what the issue was with you truck?

Sounds like a boost leak.... check the intercooler pipes/boots, and check the up-pipes, too.
