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
