Hi all, please don't flame me too bad. I've been reading and googling and trying to pin down something accurate. I was wondering if I need a programmer for an intake and an axle back? Some people say no and some say yes. I know once a blow off valve is installed then yes, but I don't have any plans on doing that until next year. My goals were a better tone and intake. I was going to try and work on suspension before stage 2. Thanks all.
