Check the full match
Check the Sloppy Mechanics Stage 2 cam identification, not just the words “Stage 2.” Stage names from other cam manufacturers do not establish a match. This is the Gen III 6.0L listing; a 4.8L or 5.3L build needs its own matching file.
Confirm the controller, operating system, transmission, fuel-system parts and supporting modifications before purchase. Review the source file against your original read before copying changes. Do not write an unmatched file directly to the vehicle.
Review the Tune Buyer Requirements beside Add to cart before purchasing.
What comes with your download
- One .HPT tune file for the application and cam named above, for reference and HP Tuners Compare & Copy.
- The JRJ video tutorial and step-by-step PDF guide included with downloadable tune purchases.
How to use the file
- Read and save your vehicle’s original file with supported HP Tuners equipment.
- Open the original and purchased files in VCM Editor. Compare the differences and copy only changes verified for your controller, operating system and build.
- Save the edited tune separately and verify the result through appropriate datalogging. Different injectors, sensors, fuel or drivetrain parts need their own review.
