Bumping an old BP thead.. has anyone had any problems with overboosting? I'm tuned on pump and E85. I'm overboosting by 2 lbs on each of my tunes. An 02 sensor code came up so I replaced that. But I'm currently not showing any codes and this has been going on for months. I think one of my wastegate vacuum lines got exposed to too much heat. The shop that upgraded my clutch might have reinstalled the lines incorrectly. Or the wastegate isn't actuating properly. Anyone have any ideas? I'm thinking about just redoing all of the vacuum lines at this point...
