What is this wire too?

What is the red wire in the pic? what does it go to? what happens if I disconnect it? what does it benefit?
I have a 2000 PSD 4x4 and asked a guy at a diesel performance shop what i can do for HP and simple mods, and he said there is a red wire behind my turbo that i can disconnect. this is the only wire I could find but it seems to be a vaccum hose. Any help is appreciated.

yep thats it. just pull it off the actutor, and attach it to one of the intercooler boot clamp bolts on the end. That way you wont get any dirt in the vacume line. It will take away the normal functions of the wastegate, and it will spool longer, and eventually the spring will give in the wastegate and stop making boost. some people see 6-8 PSI more boost.

All you do is put the red hose onto one of the bolts holding the inner cooler clamps on to keep it from wasting boost pressure. The valve is spring loaded shut and pressure from the red hose forces it open to bleed off excess boost. 94-97 trucks don't even have a wastegate, they are on 99-03 trucks, vans don't have them either. Some folks notice some difference with it disconnected.
