boost control problem?!!
hey guys i have a hallman evolution pro series controller that i have installed.
I checked the boost source input and wastegate output lines on the controller and everything is fine. I turn the controller to the lowest boost setting and monitor on my gauge and i see that the boost isnt regulating as it can exceed 10 psi when i want it set at about 8 for now.
Do you think it is my wastegate that has a problem?
I have a stock s5 TII motor, 720 cc secondary injectors, straight 3 inch turbo back, and a knightsports fcd.. Any help would be appreciated thanks guys.

Yeah it's probably your wastegate. The stock wastegate doesn't keep up very well once you have a big free flowing exhaust. Search 'port wastegate' or something similar, doing it well usually involves cutting the openings bigger and welding washers to the actuator arm(s) to cover the now larger ports. Takes a little time, but it's definitely worth the safety and control. Pull the hotside cover off to port and have a machine or exhaust shop do whatever portions you can't do. I ported my own and had a muffler shop weld my washer on, they might have charged me like $10 and it was a nice clean weld I couldn't have made with my cruddy 110V gasless MIG welder.

yeah i eliminated the stock boost control solenoid. I removed both vacuum lines from the tid and wastegate and plugged them. Do i also need to unplug the solenoid from the harness?
Im thinking that the issue might be my wastegate since i have a freeflowing exhaust. But before i jump to conclusions i will test the mbc and wastegate with an aircompressor. thanks guys
