Message Ok, I have been trying to get my boost controller dialed in, and I just can't get it. I have tried the different dipswitch settings on the back, and everything that I can think of.

This is what is happening:

I take the control box out of the picture and put the hoses together with an "I" connector and hose clamps, and my Z is fine, only runs about 10lbs or so(which is fine by me...for now) when I hook them up the box, it is a different story. It is my understanding that if you turn the controller off, it should act like stock....but I am boosting 15-16lbs. when I turn it on...with all settings to minimal, it still boosts 15+lbs. I know that is OK for Z's but, I am NOT wanting to boost that much right now. just 12 or 13 lbs is all that I want, but I can't get the controller to do it. Even with the damn thing off!!! What am I doing wrong?!??!

I know there are no leaks, because if there were, I would not be holding at 10lbs with the box out of the picture. So what is going on? Please help me!

thanks in advance

More pics of my rides and family this way!
