I’m just now getting a startup tune for my car after about a year of sitting, still dialing it in. While it’s trying to idle, the boost gauge is reading 5-10in of vacuum and if I tap the gas it actually goes down showing more vacuum. It will go to around 15-17in of vacuum if i tap the throttle or hold it steady around 2500rpms. Has anyone experienced anything like this? It’s an electronic autometer c2 gauge. Checked vacuum lines and nothing seems out of the ordinary or leaking.
