Will a delete kit void my Nissan warranty?

Yes. Any DPF or EGR delete modification will void Nissan's powertrain warranty. Most owners accept this tradeoff because factory repairs (DPF cleaning, EGR cooler replacement) run $1,500-$3,500+. Once you delete, you're done with those failures.

What's the difference between a full delete and just the DPF delete?

A DPF/CAT delete removes the filter but leaves the EGR system active. A full delete removes both DPF and EGR. You'll gain more power and reliability with the full delete, but the DPF-only route still improves fuel economy and eliminates DPF clogs.

Do I need a tuner with my delete kit?

Yes. The factory ECU will throw codes and run in limp mode without a delete tune. The Ez Lynk Auto Agent 3 rewrites the software to match your new exhaust and emissions configuration. It's not optional—it's required for the truck to run properly.

Is the Ez Lynk tuner hard to install?

No. It plugs into your OBD-II port under the dash (takes 30 seconds), and you tune it via the handheld device or smartphone app. Installation is a 15-minute job. You can even switch between custom tunes if you load multiple profiles.

What's the mpg gain from a full delete?

Most owners see 2-4 mpg improvement after a complete delete and tune, depending on driving habits. The gains come from reduced back-pressure (your turbo works less hard), cooler EGT temps, and the ability to run optimized fuel maps instead of the factory's conservative emissions tune.

Can I install this myself, or do I need a shop?

Both are doable. The Ez Lynk tuning is DIY-friendly. The exhaust work is bolt-on but requires basic tools and a lift or jack—most shops charge $2-4 hours labor. If you're comfortable under a truck, you can handle it yourself.

Will this affect my truck's towing capacity?

No. A delete kit and tune actually improve towing by increasing torque and lowering EGT temps under load. Your truck will tow the same weight but with cooler, more consistent power delivery.
