So i brought the greddy type s just for the simpliscity of how to use it, im currently running a .8 bar wastegate spring(blue spring) and for low boost i set it off the wastegate spring which boost and hold fine but when i try the high boost setting with the knot turn to min so it should still be at wastegate spring but whwn we try it, we hit the boot cut which is set at 15 psi and i have no way of lower high boost setting lower??? I would like to set my high boost at 16 psi, do i need to go with a smaller spring or something? we only did like 2 pull and both time it hit boost cut, im gonna try and work with it some more but does anyone have any experience with it.

 

I assume this is an older Greddy boost controller, the older units have dip switches that allow you to adjust gain. You might want to download the instructions and make sure the dipswitches (if it has them) are set properly for your setup.

 

all the way to min, still hitting boost cut... Low boost work fine tho?
