yes its adjustable , I am using an adjustable 2-10 bar pressure switch, I have it set at 85psi , since I run about 130psi line pressure. Some may say that this addition is unnecessary , but with a 1000 hp bb turbo that gets to full boost (25+psi) by 3500 rpms , I can detonate with very little boost pressure since the air flow is quite high. I also have my ignition maps advanced a bit to help enhance the boost response and low boost performance.
