sounds like i have a short somewhere or something. my boost controller will constantly read 208kpa (30psi), when ignition on, idle & running. it will sometimes randomly read the right vacuum/boost numbers but will only last a couple minutes if that. happened just randomly & kept getting worse, until now the boost controller is useless & constantly kept off. wondering if anyone has had similar problems or any advice on what to check.
