Hey, so this guy is selling an 04 Wrx and it been talking to him. He says It will need to be towed because you can't drive it till its tuned tune or else u can possibly blow the engine. It has bigger injectors, sti inercooler, perrin silicone hoses, bigger fuel pump, perrin cam gear. Do you really need a tune for these things? Or is he trying to sell me a piece of poo?
