Test drove the GTP Saturday and wasn't impressed by the power. I could hear the supercharger, but it wasn't pushing me back into the seat. I've got a 2006 Malibu 3.5L V6 with an intake and a better flowing exahust. The Malibu pulls harder than the GTP did!

I'm thinking since the owner only put gas in it and took it to a mechanic for oil changes, that he didn't do much else with it. I'm betting that his air filter is all clogged up and needs replacing. What do you guys think?
