LS turbo... T3/t4
Tial 38

Just put on a Turbosmart Manual boost controller
Hits 11lbs then creaps back down....

whats the problem?

havent taken a look at it yet... just wanted some ideas

 

put the boost controller as close to the wastegate as possible, with little vacuum line run as possible.

 

Theres always the obvious.(no offense) Check the IC plumbing for leaks, check the wastegate for cracks, and make sure your BOV isnt leaking under boost. It may be just bleeding off enough not to notice, especially with an open wastegate. Good luck

 

make sure all your hoses are on too, me and Sean found a huge as leak where his boost gauge line was, something minor, so make sure u check all of em

 

mine did that too. I didnt know it, but the boost guage line cmae off the T and it sounded loud as a bitch, i was like" why does my turbo sound so loud?"
