I recently just purchased a Greddy Profec Spec 1 boost controller (The older one with the hi/low boost setting *****),and had it professionally installed.However,I wasn't actually shown how to control the boost myself,like if I want to turn the boost up or down.I purchased it used,so I don't have a manual or anything..I was wondering if anybody was very familiar with this controller and could help me learn how to set the boost levels myself..Any help will be greatly appreciated!

By the way,it's currently set to run stock boost..I'm hoping to set it to run ~12 psi

 

the .pdf instructions are floating around here somewhere.
