Does anyone have any experience with a hallman boost controller? When I got my car it was kind of a hack job swap & was only running off the wastegates. I installed a hallman pro mbc to get me by. Up until recently I was running 10 psi & it has been rock solid. That was with the light spring & ceramic ball. I got a sz chip so I'm trying to run 15psi now. The light spring maxed out at 12psi so I installed the heavy spring. I now get a spike to 15psi & it drops back to 13. Just curious if the steel ball could help with spiking as it supposedly reacts slightly slower. I'm going to order one but just curious if anyone else knew the answer. I know a good ebc is the ultimate answer.
