Will tuning software void my truck's warranty?

Yes. Once you flash custom tuning software, most manufacturer warranties are gone. That's the tradeoff. Some owners accept this risk for off-road use; others keep stock tune for warranty coverage and flash custom tunes only when needed. It's your call based on your truck's use and your risk tolerance.

What's the difference between handheld tuners and bench flash?

Handheld tuners like EZ LYNK and EFI Live let you reprogram your truck yourself anytime. You control everything. Bench flash tuning means you send your modules to us and we reprogram them—zero learning curve, but less flexibility if you want to adjust later. Both work great; it depends on your preference.

Do I need to delete my DPF and EGR to see gains?

No, but you'll see bigger results if you do. You can tune a stock truck with DPF and EGR intact and still gain horsepower and fuel economy. Deleting those systems removes the biggest restrictions, though, so most tuners recommend both for maximum performance. Start with the tune alone and upgrade to delete kits later if you want.

How much power can I actually gain from tuning?

It varies by engine. A 6.7L Powerstroke or Cummins can easily pick up 50-100+ extra horsepower and 100-150+ torque with aggressive tuning and deletes. Even mild tunes add 30-40 hp. A Duramax LML typically sees 40-80 hp gains depending on the tune level. EcoDiesel engines are more modest but still see meaningful improvement. Ask us about specific numbers for your truck.

Can I switch between multiple tunes on the same handheld tuner?

Yes. EZ LYNK and EFI Live let you load multiple tune files and switch between them. Some guys run a towing tune for hauling and a economy tune for daily driving. You control it all from the handheld device—takes seconds to swap.

Is bench flash safer than handheld tuning?

Not inherently. Both methods use proven, tested tuning code. The safety difference comes down to the tune itself and your driving style. A conservative tune is safe on any platform. An aggressive tune on a stock transmission is risky whether you use a handheld or bench flash. Buy quality software and tune to your truck's capabilities.

Do I need anything else to install tuning software?

For handheld tuners, you just need the tuner unit and a laptop/phone to connect it. Bench flash requires shipping your modules. No special tools needed. If you're doing DPF deletes at the same time, you'll want ourdelete kitsand intake/exhaust work, but tuning alone installs in minutes.
