Not only is the tuner initially programmed to your specific truck as it is, but the truly great thing about these Autocals is that you can do so much more than just program!

For customers who frequently upgrade their truck, tunes and data logs can be exchanged with Punisher Performance via email!

Share your tunes

Each Autocal comes with one VIN license which allows you to tune one engine and one transmission. Additional VIN licenses can be purchased for $125, in case you trade trucks or have a friend who wants some tuning! Each device supports a max of 7 licenses.

Flo~Pro DPF and CAT Delete Pipes

Flo~Pro's Race Delete Pipes replace the DPF and CAT systems with 4" straight pipe. They do not require welding or modification and install easily using OEM mounts and hanger locations. Flo~Pro has put decades of experience into every pipe they build, while still offering affordable prices. Their longer, contoured welds on the hangers and machined flanges show they have learned from the mistakes many manufacturers still make.

  • The Steel: Mandrel-bent 4" Aluminized Steel tubing.
  • Multiple Benefits: Your freer flowing exhaust increases HP and Torque, while reducing EGTs and eliminating "Regen" cycles which saves you fuel.
  • Simple, Secure Installation: Pipes bolt on using OEM hangers and mounts. In most of their systems Flo~Pro uses Torca clamps to keep the pipe round, as it was intended. No cutting and no welding required, so you know the fit is solid.
  • What's Included: Kit includes the pipes and all necessary mounting hardware.
