Hey paultvx, I'm in the same boat as you. I know excactly what you are talking about and I think the both of us need to back the line preasure down to maybe 15% It just gets more and more annoying, I have had mine on for about a month and a half now. I just haven't had it cool enough to adjust when I think of it.
Sorry Technocoy, I really don't know if it would help or not, maybe have someone that has the interceptor installed, drive your car to see if it would help in your case.
