the first turbo is boosting 4 and the second is boosting 5 does anyone know why this might happen i checked the IC pipes but they were all together my mods are 3mm apex seals, street port, dp, high flow cat, cat back, and intake, it used to push 12 psi can anyone explain this. thanks

 

Iäm not 100 percent.. but my car did this.. i checked everything.. until i checked one of my couplers... it had a cut.. and boost was leaking out.. I would check all the couplers as well as the pipes.. hope you find the leak..

 

May be this my help but don't hold your breath. When I had the boost problem one of them was that the intake pipe that goes to the throttle body was cracked. The way I found out was when I was trying to get the pipe out of the intercooler and then I notice it.
