okay, so i know i had it hooked up wrong before. so tonight i went out and fixed the hose connections that weren't correct. i connected them to match the diagram on greddy's site:

vacuum port on compressor housing -> IN port on profec motor
top port of wastegate -> OUT port on profec motor
side port of wastegate -> vacuum source
and of course the profec controller is hooked up to vacuum also, dip switch settings set to external wastegate

with the boost **** all the way to 0 i boost at the wastegate spring level, with it turned all the way up i still boost at the wastegate spring level..

any ideas? this is quite annoying.. i want to see the world past 4 psi

 

"vacuum port on compressor housing -> IN port on profec motor" is not right.
The in port you try to hook up to the compressor housing is connected to the pipe after the compressor before the throttle body. Never tried the compressor housing method but this is strictly told by greddy them self. Profec provides the threaded connector for you to tap into the pipe. Remember, it's not the pipe with the air filter connected with but any sections after the turbo around the intercooler or the charge pipe. Mine is run perfectly fine with this method, it is not showned on the instruction either.

 

 

i assumed running it from the nipple on the compressor housing would be the same as the charge pipe.. i guess not. i'll go correct it soon.. thanks!

 

Adam, It is the same.. that shouldn't be the problem.

 

that's what i thought, and so did a few people who have installed them before.. guess i'll keep looking.. thanks
