An economy-focused calibration optimizes the things that quietly waste fuel: fueling strategy, timing efficiency, torque delivery that stops asking the engine to fight itself, transmission behavior that holds the right gear instead of hunting. On a machine that works for a living, small percentage gains multiply by every hour and every gallon.

The honest caveat up front: your right foot and your duty cycle matter. That’s why we measure — datalogs before and after, on your machine, doing your work.

As an authorized Viezu dealer, we write BlueOptimize™ — Viezu’s own economy-tuning program — right here in Fort Wayne. Their published record, which we quote rather than invent:

• Typical fuel-economy gains of 10–15%, up to 20% in fuel-cost saving — Viezu’s published figures
• Installed on 150,000+ vehicles worldwide
• The software behind Viezu’s Queen’s Award for Enterprise (2014)
• Independently tested at the Millbrook proving ground
• Written for cars, vans, trucks, fleets — and tractors

Those are their numbers, earned across their network. What matters for you: we measure on yours.

• Work trucks that tow and haul every week — 6.7 Power Strokes, Cummins, Duramax
• Fleets, where a percent of fuel is a line item someone answers for
• Farm equipment, where fuel is one of the season’s biggest costs — the ag version of this story lives at agmerica.farm
• High-mileage daily drivers where economy beats bragging rights

How much fuel will I actually save?

Viezu publishes typical gains of 10–15% across their program. Your machine, load, and duty cycle decide your number — which is why we datalog before and after and let the measurement answer.

Does an economy tune mean losing power?

An economy calibration prioritizes efficiency, but it’s not a punishment tune — drivability and usable torque are part of the goal. We calibrate to what you ask for, and many customers blend goals.

Do you do fleets?

Yes — and we come to you, over a 100+ mile radius of Fort Wayne. A typical mobile visit covers multiple units in a day. See how mobile visits work.
