I haven't decided to go n/a or turbo yet but my question is when do you tune. When I install a set of na cams or a turbo can I drive till I go tune or drive right after the install to go tune or get it installed and tuned by the same guys? And does it go "the longer the dyno tune the better the tune"? They charge 150/hr and I dont want to be cheap but thats alot. Also when they do a tune they sell you the chip there and tune that right? I know I could just call but I rather compile as much info here as possible in case i should be doing some shopping around for tuners first.
