my friend has a profec b on a deltagate hooked up as everyone said here(side port to manifold, and top port to "out" on greddy box) and it seems to only want to boost about 16psi with both ***** at full right. does the position of the wastegate spring have anything to do with this? and we have pressure checked the charge pipe and its ok, and the turbo is more than capable of more boost. any suggestions? we tried swapping the lines at the wastegate and it spiked to almost 30 psi with both ***** at min, so that isnt the asnwer.
thanks,
Jared

 

Try the compressor nipple to the "in" on the solenoid and the side port of the wg to the "out". Leave the top of the WG open to air.

Thats the ONLY way I could get my set up to work.
