i hab my intercooler off today to try a mates one on my car and now with mine on its boosting to .8 instead of 1 bar.everything is on properly and im not running with the standard boost solenoid so its not safe mode.it runs exactly the same just lower boost.any ideas why?i was thinking the hose with the dump valve may be leaking as it looks a bit sus but wouldnt an air leak just make it take longer to get full boost?
