boost pattern and mbc question
 

hey guys,
My boost pattern on my car is 10-12-8 in third gear and ordered this boost controller (see pic below) and was wondering if i hook it into the wastegate control or the turbo precontrol hose to get that 8 up to 10? Im guessing it goes in the wastegate control hose but just want to be sure.
thanks,
Craig
