the turbo does need to heat up. even though temp gauge says engine is warmed up, the turbo needs to be hotter. you don't want to get on it until then. does it make the hissing sound at idle? or just under boost?

Sounds like a healthy vac leak somewhere in your system.
Start checking your intercooler hoses, the BOV ... make sure the big hose that connects to the front of the turbo is nto cracked.

Vacuum leaks seem to be the issue of the month. How can you track vacuum leaks down other than visual inspection?

it might be a vacume leak like u said..you can hear the hissing sound after i pull it a lot...that sound will stay there as long as i drive it..but if i drive normally then nothing happened
