About Integrated Engineering
Integrated Engineering machines its performance hardware in Salt Lake City and develops its own ECU calibrations in-house — a rare combination that means the parts and the tune are engineered together, not bolted together.
What makes Integrated Engineering different
IE controls the whole chain: billet manifolds and forged internals from their own CNC shop, validated with their own dyno-developed software. When a kit says 450hp capable, it’s because they built and broke the prototypes first.
