i have a two stage greddy profec II boost controller. on high its set to 10 psi. however on low i have it set at my tdo5 18g stock wastegate pressure of 6psi. it seems that i cannot get it to stay at 6psi anymore. it seems to creep to 8 and then fall to 7...... could my spring be bad. is this too low a pressure for the greddy boost controller to sense. I wouldnt think so.

any thoughts.

well, since you spent the cash on a name brand boost controller, why not spend some cash on a real wastegate?

then your creepin issues will be fixed
