A little confusion with the BCC, Can I run the BCC without a boost controller? Is the bcc at all tunable with the use of a boost gauge?

you will have the get a bcc BEFORE you get an ebc/mbc or else you just wasted $300+. the bcc is "tunable" but does not control boost. the "tuning" done on the bcc is done with a screw to dial in the correct voltage. too much/little and the bcc wont function correctly.

I guess what i am trying to figure out is what the tuning of the voltage does? If it does not control boost levels then what do the adjustments "tuning" do to affect the performance. Before i install this little beauty I would like to know if i am going to adjust the wrong way and blow up my sup-dawg

all the info you'll need.

Okay, I read it a couple times & I think i get it. Correct me if i am wrong, i should not install the BCC without a boost gauge or boost controller? Without those items I could boost out of control or spike above 18psi?
