Dipstick popped loose? Other "oddness" after chaging air meter

[Will_w202]

I changed my AMM last week, HUGE difference in power, upon first kickdown I smelled something like burning oil and rubber , but it hasn't done it since, just blistering acceleration (from a 2.3) compared to what it used to be.

Yesterday, I also noticed my dipstick about an inch outside the tube! WTH? Where would pressure have built up to cause that?
