Our Guidance
We generally recommend SCT unless there’s a specific reason to choose HP Tuners.
SCT is easier, more affordable, and ideal for most daily-driven vehicles. It’s also good for moderate LS swaps. If budget is tight and you’re not running heavy mods, SCT is the way to go.
Choose SCT if you:
- Have a daily driver with stock or mild bolt-ons.
- Want reliable, dyno-proven preloaded tunes immediately.
- Would like easy access to our custom tune service.
- Run long tube headers and need rear O2 disabled (custom tune required).
- Need features like DOD/AFM/MDS delete, speed limiter removal, transmission tuning, fan control, etc.
- Have an LS swap that does not require a segment swap (Gen 4 ECUs still require mail-in for VATS delete).
Choose HP Tuners if you:
- Have advanced builds (Stage 2+ cam, boost, high-stall converter, etc.).
- Are tuning GM Gen 5 (DI) with cam upgrades.
- Own a 2015+ Dodge/Chrysler/Jeep (unsupported by SCT).
- Need to tune more than one vehicle.
- Want full parameter access or plan to self-tune.
- Require VATS delete on Gen 4+ GM ECUs.
