***THIS IS THE PACKAGE INSTALLED ON OUR
RECORD HOLDING SBE 392 CHARGER SCAT PACK***

Introducing the SaT.Tun Level 4 Package for the 5.7/6.1/6.4 Platform. 

This isn’t just “another upgrade” — it’s a full-scale performance transformation for your HEMI platform, executed with the same meticulous care that defines every job we do.

What’s included:

- Custom-spec camshaft + full supporting valvetrain components (for 5.7L / 6.1L / 6.4L HEMI platforms).  

- Long-tube headers of your choice 
--- Stainless Power 1 7/8″ w/ HFC
--- Stainless Works 1 7/8″ w/ HFC
--- Kooks 1 7/8″ w/ green high-flow cats)

- In-house PCM unlocking for 2015+ models. 

- Smart Access Cable installation for 2018+ models. 

- RTD tuner device + all credits required for tuning. 

- Full in-house installation of all components — we don’t half-measure.

- Street-drivability tuning + complete PCM & TCM calibration on our dyno.

- Typical gains: 60-75+ wheel horsepower (varies with model, condition, and prior mods). 

Why this package stands out — the SaT.TuN difference:

- Precision removal & install: We treat every vehicle as though it were our own. When removing the factory cam, valves, headers, etc., we take extra time to disconnect, label, route and secure everything so no detail is missed.

- In-depth inspection at every turn: While installing the new valvetrain and headers, we examine everything we see or come in contact with — hoses, wiring, connectors, sensors, manifolds, seals — if it’s within reach, we check it.

-Meticulous surface-prep: Before installing the new cam, valvetrain gear and headers, we clean all mating surfaces, remove old gaskets, carbon residue and build-up so that everything fits flush, seals properly and starts from a perfect foundation.

- Smoke testing for assurance: After the install, we apply smoke tests to the intake and exhaust systems, verifying that all joints, seals and connections are airtight — ensuring your upgrade is locked down and primed for performance.

- Small details, big impact: Anti-seize where needed, correct torque specs, proper thread engagement, clean wiring loops, clear labeling, and tidy hoses — these are the “minor” steps many skip, but we don’t. They matter.

- Holistic execution: This is not “we install the header and hand you off”. We provide the full service — installation, tuning, calibration and hand-off of a vehicle that’s ready to go, with performance gains you can feel and hear.

Who this is for:
If you’re driving a 5.7L, 6.1L or 6.4L HEMI-powered vehicle and you’ve already gone past basic bolt-ons, this package is built for you. You’ll get sharper throttle response, stronger mid-range and top-end power, enhanced sound (thanks to the long-tube headers), and most importantly — the confidence that your build was done right, down to the last detail.
