well if mpgs are your #1 priority, then yeah i'd say probably not based on what i'm getting. however i'm only one v8 owner, and i'm definitely usually heavy footed (i have to -try- when i want to grandma it).
however if you're ok with losing a couple mpgs for a TON more hp, then you really should get it
i thought racerx had a bully dog too though, wonder what he's getting
