If you already own an EZ Lynk AutoAgent 3 hardware device, you can select the BYO (Bring Your Own) Device option and simply purchase the tuning package. If you do not already have a compatible device, we offer the AutoAgent 3 as a convenient add-on option so you receive everything required to flash and monitor your truck straight out of the box.

Our kits are designed with straightforward bolt-on components suitable for confident DIY mechanics with standard automotive hand tools, or any certified diesel performance shop. If you or your mechanic have questions about labor, sequence, or hardware fitment, text our tech team directly at (512) 522-9403.

This allows you to split high-ticket purchases (from $600 to $2,250+) into predictable, budget-friendly payments instead of paying the entire total upfront. Simply choose Shop Pay as your payment method at checkout to see your rates with no impact on your credit score.

Free shipping is included on all orders across all 50 United States. Whether you are ordering a single component or a heavy all-in-one exhaust package, standard shipping is 100% free with no surprise handling fees.

Here is exactly how our custom tuning workflow works from order to flash:

• Step 1 — Order Confirmation & VIN Collection: Once your order is placed, our team reaches out directly to receive your 17-digit VIN and vehicle setup details.
• Step 2 — Device Arrival & Connection: Once you receive your tuning hardware (such as the EZ Lynk AutoAgent 3), plug it into your truck's OBD-II port and link it with the app.
• Step 3 — Custom File Delivery: As soon as your device connects to your vehicle, we send your custom tuning files library built specifically for your truck straight to your account.
• Step 4 — Flash & Drive: Flash the calibrations directly onto your vehicle. If you ever need guidance during the flash, text us directly at (512) 522-9403.

We provide direct, dedicated support for all customers before, during, and after installation. You can text or call us directly at (512) 522-9403, send an SMS message, or email us at slabindustriesdiesel@gmail.com. We are based in Central Texas and pride ourselves on fast, knowledgeable assistance.
