what do you think of a mercedes airbox and a TB.
which one works better along with a tune.
is there any tunes where you get a free retune when you add mods.
For the look of a stock appearing engine, go MB airbox. For the most HP gain, go CAI. They will both work very well with a tune. Our TVT265 kit uses either a MB airbox or Intake and both make roughly the same power with the airbox giving up a little on the top end for more low and mid torque.
As for tunes, most mods will not need a retune. We offer free retunes if the dealer flashes over your file though. If you do something radical like cams then a complete retune is needed and there is a discounted rate for that.
