My car (mods in sig) is currently at a local shop getting some light restomod work done. The shop owner has been a Mustang guy pretty much for life, but while discussing possibly throwing in a cam while my motor is out, he mentioned that both a B303 and E303 cam would require tuning and chipping the computer...which is contrary to what I remember (granted, from when I was really into our cars about 10 years ago). Do both cams require tuning, if I've already converted the car to MAF? Do any cams not require tuning? Just trying to avoid turning a $300 upgrade into a $1000 upgrade.
