[2.0AUTO_TURBOLESS]

does anyone know what i can do to a 2002 automatic gls with no turbo? i was thinking a ECU, catback, and a short ram intake. I can get the short ram for $80. I found a PCD performance chip online for $80 and its suppose to add 50 HP. Im new to VW's and need advice, why are people telling me chips are like $300?
