Hey guys so last year I installed the upgraded piston DV from ECS . Few months back I also purchased from ECS the Atmospheric Diverter Valve Spacer. I just installed it however I feel like now boost comes on later on the RPMs . Before it was at 2800rpm, now it's after 3k.
Do you loose power for running atmosphere valve? Since the air is not going back in motor but released out? Can anyone confirm this? Also how can I test boost leak or boost drop using VAG com or other methods? I do not have boost gauge. I do have OBD Bluetooth scanner which reads most parameters but I don't think it's accurate.
