Vehicle fitment & exclusions

Will this fit my truck?

Every product is confirmed to fit the trucks named on its page. If your year, cab or chassis config is unusual, call us and a tech will confirm fitment before you order.

Do I need to unlock my truck first?

Some late-model trucks need a factory security bypass before tuning. If yours does, the kit includes the unlock hardware or we'll flag it before shipping. Call a tech if you're unsure.

Can I install this myself?

Most customers do. Basic hand tools, a driveway, and the included step-by-step guides are enough, and our techs walk you through the flash by phone if you want backup.

Very happy with this kit.

Total game changer for my 2025. Came with good instructions as well. Customer Service was very helpful.

Quality is top notch and the truck just feels alive now.

I was excited before ordering, but after installing it I’m blown away. Power delivery feels clean and strong, and the whole process was smooth from start to finish!!!

10/10 Recommend!!!

I wasn’t expecting a huge jump in performance, but the difference on my 2025 is very noticeable. The truck accelerates more smoothly and doesn’t feel restricted anymore. Merging into traffic and climbing hills takes less pedal, and overall it just feels more responsive.

Owning the truck feels different now in a good way. No more dealing with emission system headaches, and the overall experience is just simpler and more enjoyable. Five stars from me.

Very satisfied customer!

Was constantly fighting check engine lights. After deleting, my truck runs flawlessly smooth, strong, and trouble-free. Empire Diesels actually care about their customers. I’ve dealt with other companies that just sell the product and disappear, but these guys were there every step of the way. Thank you!

Amazing experience!

The installation instructions were clear and easy to follow, even for someone like me who isn’t a professional mechanic. The tuning was simple and worked perfectly the first time. I’ve also noticed my engine runs cooler and doesn’t sound like it’s struggling anymore. I couldn’t be happier with the results. It’s worth every penny and then some. Their team answered every single question I had. Amazing experience!

Couldn’t ask for better quality.

I’m impressed. The tune woke the truck right up. Tons of torque, smoother acceleration, and better fuel response. Finally free from all the DEF and filter issues. Thank you Empire Diesels.
