cams

i have an '02 z28, a4. i was wondering if the gm 1200-6000rpm cam would be okay for me. also, what all has to be done for this to work? is there a lot of work and tuning involved? i need help with this, thanks.

What other mods do you have? It being an A4, get a converter first.

i suggest before getting a cam, get a set of longtube headers, and gears if u dont already have it. with the cam u will need to buy other parts for it as well like springs. u will definently need a tune which will probably cost like $400 to $500. a cam requires a reprogramming of your ecm.
