Step 2 of 8 — Engine

Select Your Engine

Select your engine from the platform you picked on the previous step. This keeps the builder simple and avoids duplicate car/truck choices.

Step 3 of 8 — Camshaft

Camshaft Setup

The cam is the single biggest factor in your tune file — it directly affects idle RPM targets, VE tables, airflow, fuel trims, spark advance, and torque management.
