Stage 3 Fiesta ST on e40 with Custom JSTUNED Dyno Tune

We had the the opportunity to custom dyno tune a customer's Full Bolt on Stage 3 Fiesta ST at our facility. We wound up making 228whp/330wtq! The gains over the entire power band were pretty remarkable, and you can definitely notice a difference from the drivers seat!

Modifications include:

DHM Front Mount

Tial BOV

E40 Mix
