3. HP Tuners Universal Credits - 8 Universal Credits are required for programming the ECM and 4 Universal Credits are required for programming the TCM (TCM is optional and can be done at a later date).
4. Unlocked T87A TCM - This is required if you are doing a transmission tune. The factory TCM must be unlocked prior to tuning. This Unlocked TCM will actually replace your factory TCM.
