If it has an ECU, the odds are good. We calibrate gas and diesel engines across cars, trucks, farm equipment, and plenty of things in between — running six professional tuning platforms so no single tool’s coverage limits what we can take on.

The fastest way to check your exact machine: the “Can we tune yours?” lookup on our homepage. Pick your make, model, and engine and it checks our coverage data — tens of thousands of vehicles — and tells you how we’d connect to your ECU and whether it’s a locked late-model unit.

Plain list, no adjectives:

• Diesel trucks: Cummins, Duramax, Power Stroke — work trucks, tow rigs, fleet units
• American gas: GM LS and LT, Ford Coyote, HEMI — daily drivers to built motors
• Import and Euro: Subaru, BMW, Volkswagen and Audi (gas and TDI), and most anything OBD-era
• Agricultural & heavy equipment: John Deere, Case IH, New Holland, AGCO, Kubota and more — see our sister brand Ag’merica
• Transmissions: TCM calibration on many platforms, including Allison behavior

Every calibration is built from scratch for the machine in front of us — a dynamic tune, not a static off-the-shelf file. It’s the name on the door.

Late-model trucks and performance cars often ship with locked ECUs — B58 BMWs, L5P Duramax, the Hurricane 3.0, Elantra N, and others. Locked doesn’t mean untunable: many of these can be unlocked professionally before calibration. The lookup flags lock status for your vehicle, and our ECU unlocking guide explains what that process looks like from your side.

One sentence gets you a real answer:

• Year, make, model, and engine (the engine matters more than the badge)
• Any modifications — installed or planned (intake, downpipe, turbo, injectors, E85…)
• What you want out of it: power, economy, drivability, towing, sound

Send it through the contact form, call or text 260-355-1123, or book directly. If your machine is unusual — marine, powersports, a swap — ask anyway. Unusual is a normal day here.

My vehicle isn’t in the lookup — does that mean you can’t tune it?

No. The lookup covers our mapped coverage data, but plenty of machines we tune aren’t in it — call or text with the year, make, model, and engine and we’ll give you a straight answer.

Can you tune a swapped or carbureted engine?

If it runs on a tunable ECU — like an LS swap on a factory or standalone computer — usually yes. Carbureted engines without an ECU aren’t a tuning fit, but tell us what you’re running and we’ll point you the right way.

Do you tune marine engines or powersports?

We’ve tuned marine and powersports units where platform coverage exists. Ask with the exact engine and we’ll check.

Do I have to bring it to you?

Not necessarily. We’re mobile over a 100+ mile radius of Fort Wayne — we come to your driveway, shop, or farm. Remote flash is available on select platforms. See how mobile tuning works.
