A tune does many things
Better take off
Better mid range power
Better over all driveability
More performance and much much more
I charge 395.00 shipped for the SVT Focus and that comes with a full custom tune not the cookie cutter pre loaded tunes some shops send out , FREE updates as you add more mods , I was the first to tune the SVT Focus and I own one
