Throwing this up for a friend. He is using a turbosmart 45mm progate with a turbo xs dual stage manual boost controller. When he uses the 7lb spring he can control boost from 7psi all the way to the springs max wich is 17.5psi. Now the problem is he wants to go to 20psi but the gate opens at 17.5 so he has to toss in the 14lb spring. When he does this he has no boost control at all. He says that the boost immediatly spikes over 20psi in less than a second and cannot control it. If he switches back to the 7lb spring all is good again. He has called turbo xs and turbosmart and they have no idea what could be wrong with it. Is his gate too small or something?
