how do i take the top off of the boost controller to change the spring? cause right now it is boosting at 25psi + turned all the way to the left, i was trying to set it and everytime the boost gauge started to reach around 24 psi i just let off cause i am not trying to blow my motor. i bought it used so i dont remember what he said he had it set to. but i just want to run 18 or 20 psi so i guess i need to change the spring. any help would be great. thanx

 

nvm i figured it out
