DiabloSport i2 Tuner for 2014-2016 only! Ford Fiesta ST *FREE SHIPPING

$ 399.95 $ 444.95

The Ford Fiesta ST is a sporty ride but there was a lot of power left on the table from factory and unlocking that is what we do!  We strapped the Fiesta down to the dyno and got to work!  We’ve optimized the tuning and added max gains of 50 HP and 89 LB-FT of torque to the tires!  We made huge gains on the bottom end to increase responsiveness and make this car a blast to drive!

We know power is always the main goal in performance tuning but we always strive to make sure you have the custom options to make tweaks to optimize the product yourself.  We have enabled custom options like tire size calibration, cooling fan control, timing and fueling adjustments, speed/rev limiters and more!

Now you can take your Fiesta ST to the next level with POWER YOU CAN FEEL from DiabloSport!
