do u have a boost gauge? a profec b is just a boost controller and u need a boost gauge to set a safe amount of boost.

actually, you need the boost gauge just to verify that the boost controller is doing its job (by reading the current PSI)

unless if that's what you meant

The profec b spec II has a digital boost gauge built in. The thing I hate about the Spec II is that it spikes/creeps a lot especially with weather change. Tuning on it sucks. My selenoid took a crapper on me after three months!

But set it to 12 psi which is .80 and 1 bar for the other setting and you should be cool. The other tuning options are pretty much up to you. Test and tune buddy.
