i have a 05 5at coupe with CAI, 5/16 plenum, stillen grounding kit and megan test pipes. getting catback soon(thinking of greddy evo2 but i'm not sure if it needs a y pipe) and maybe lightweight pulleys. then getting turbo xs utec engine management and a good tune from mrd motors in norfolk, va. i was told by a friend to get bigger fuel injectors but after talking to skott from mrd he said our stock injectors are 370cc and can handle up to 400 hp but i will likely get about 280 to the wheels if the tune goes well. i will chill on that setup until i have enough $$$ to either port and polish the heads, get brian crower cams and stainless steel valve springs, or go f/i and get a turbo kit. oh and being an automatic i'm getting a valve body upgrade cant wait for that
