WHAT YOU GET

In the box.

01

A calibration written for your car

Per-chassis, per-engine, per-DME map. Not a global flash.

02

Datalog review before sign-off

You log it, we read the numbers, revise if anything's off. Standard policy.

03

bootmod3 license included

Authorized dealer. License paired to your VIN.

04

Reversible. Documented.

Stock revert before dealer visits. We write down what changed.

ORDER

Five questions, then we calibrate.

The Path Finder asks for the year, chassis, model, fuel, and any supporting hardware. Two minutes; checkout ships your VIN-paired license and a datalog request. The tune comes back inside 4–5 business days for Stage 1, 7–10 days for Stage 2.
