Real help with tuners, tune files, and setup — from people who run these trucks. Before you buy, during install, and after you're dialed in.
Picking a tuner shouldn't be guesswork. Whether you're running a 6.7L Powerstroke, 6.7L Cummins, or L5P Duramax, we'll match you to the right tuner or tune file for your truck, your goals, and your supporting mods. Not sure what pairs with your exhaust or EGR setup? That's exactly the call to make before you order — a Full Send Kit comes matched, but custom builds deserve a conversation.
Tuners marry to your vehicle and tune files unlock to your VIN, so getting the setup right the first time matters. If you hit a snag during install or activation, don't force it — reach out and we'll walk you through it. We know these devices, the common gotchas, and the manufacturer's process for getting you running.
Need something beyond an off-the-shelf tune? We can point you to the right custom tuning path for your combination and power goals. Tell us your truck, your mods, and what you're chasing — daily drivability, towing, or all-out — and we'll spec the tune support that fits.
Codes after a flash? Not feeling the gains you expected? A tune acting up is almost always fixable, and often it's a setting or a supporting-mod mismatch rather than the tune itself. Contact our team with your truck details and what you're seeing, and we'll help you sort it.
// A NOTE ON TUNE FILE RETURNS
Once a tuner is married to your vehicle or a tune file is delivered, it's final sale — the license locks to your VIN and can't be resold. That's exactly why we'd rather talk it through before you buy. See Returns & Warranty for full terms, including the 90-day manufacturer warranty on defective devices.
Tuning questions are best handled by a real person. Call a Tuned Rep at 888-322-4233 or send us a message with your year, make, model, engine, and current mods — the more detail you give us, the faster we can dial you in.
