Yes it requires a tune. a tune with our velocity stack and billet mass air meter helps with the control of air flow. Some of our customers and vendors customers have even seen a 3lbs of boost increase on a magnacharged car. If you do a search for LSR on here you will find dyno graphs and other happy customers that have purchased our CAI. If you have any question please feel free to call me, or pm me.
