My car did some huge bucking when I put in some "premium" (on a trip) that was 
more like regular - when the boost hit about 1.4, big detonation. I'm surpised 
that I didn't bend a rod that first time I stepped on it since I totally wasn't 
expecting that to happen. Did you recently fill up at a gas station that isn't 
your normal one?
