Step 1: Buy the HPTuners or full kit.

When you place your order, we require the VIN Number of your truck.

​

Step 2: Tune your truck before removing the hard parts.

Make sure that you tune your truck before you even think about removing any parts. This way, if you have any trouble tuning your truck, you’re not dead in the water with a broken truck until Monday morning when we open back up. 

Step 3: Hook up a battery charger.

Before you start, grab your battery charger and hook it up to the truck, doesn’t matter if you have brand new high-end batteries and you just finished trickle charging them to 100%. If you don’t have a battery charger, get one and set it to a 10A charge. The new ECM’s are very sensitive to voltage and the flash can fail if the voltage drops too low.
