Hey guys, I have a problem. Me and a buddy of mines did a custom twin turbo on my car. The componets consist of twin 54mm precision turbos, tial wastegates with 3.6 psi springs, these are the duel connection ones. With aem true boost controller. I cannot build more then 5 to 6 psi on a 80 % duty cycle and spring pressure at 1.6. I disconnected all lines going to the wastegates and it boosted to 11-12 pretty fast so I got off of it. My car has a base tune on it. Any suggestions guys? This has been a 5 month project with nothing but trouble. If it wasn't for Pt.Killa this project would never be where it is today, he has helped every second of the build, but we are now confused. Thanks guys
