Where did you have your boost gauge connected? Presumably on one of the existing vac ports ESS provided? If so, this is pre charge cooling and you should read more than 8psi of boost as that spec value is post charge cooling. Your 11 psi might be a tad high but probably not by much. ESS should be able to tell you what is normal for your setup. What size pulley were you running?
Sounds like things started with the misfiring, now you just need to identify the cause.
Had you been losing oil for a while or did it lose it all at once?
