Hemifever Tuning

At Hemifever Tuning, we're focussed on providing tuning solutions for your Dodge, Chrysler, or Jeep car/truck.
There is so much more to gain than sticking with the preloaded tunes on these tuners out of the box.

If it's a Hemi, DiabloSport is our choice. For your 2003+ Hemi Ram, Challenger, Charger, Magnum, 300c or Jeep, DiabloSport (and our email tuning) provides more horsepower and torque than any other tuner.

For 1996 to 2003 5.2/5.9/3.9/V10 trucks, our custom SCT tunes will maximize the horsepower output in any configuration from stock to wild strokers.

Verify vehicle compatibility before ordering.
