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.

aFe Premium DPF & CAT Delete Pipes

aFe 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. aFe pipes are expertly designed and manufactured in Corona, California and known for superior engineering, thicker, higher quality steel and providing premium hardware. This upgrade is essential for use with race tuning.

  • The Steel: High Quality 4" Stainless Steel Tubing
  • Precision: Engineered and constructed for smoother bends and freer flow.
  • Premium Hardware: Ensures leak-free 360 degree seals that stay sealed.
  • Benefits: Increased HP and torque, while lowering EGTs and eliminating "Regen" resulting in increased efficiency.
  • Unparalleled Fit: aFe precision engineering ensures a bolt-on installation without cuts or welds that will stay in place.
