HI ALL. SINCE I FOUND OUT MY TURBO DOWNPIPE IS BLOWING MY APEXI GAUGE DOESNT WANT TO LIGHT UP WHEN COMING TO MAX BOOST(1.2BAR). INSTEAD IT IS JUST OVERBOOSTING TO 1.5BAR. IS THE LEAK CAUSING THIS? DOES ANYONE KNOW HOW TO SET OR GET INSTRUCTIONS FOR THE BOOST GAUGE. IF IT HELPS IT HAS 3 BUTTONS. IT WAS ALL SET UP AND I DONT WANT TO MESS ABOUT WITH IT IF IT IS THE ABOVE CAUSING THE PROBLEM. ANY HELP WOULD BE GRATEFUL
