I have a "Dejon Tool" MBC and I forgot which direction do I turn the knob to lower the boost. Do I turn it to the left or to the right to lower the boost?
Thanks in advance guys and girls.

 

never used a boost controller but on my spray gun, right is the lower psi and left is the raise it. Righty tighty (closes, clockwise), lefty loosey (opens, counter).

 

THX Brother!

 

Don't thank him, because that has nothing to do with your MBC. Most, if not all, MBCs are opposite of that. Left loosens the spring and therefore provides less boost. If you tighten it down, you will run higher boost...

 

Tighten to boost loosen for less boost

 

Ha ha, I forgot too. I havent looked at a boost controller in about 6 months.
