SCT X4 Tuner
If you don’t already have a hand held tuner you’re going to need one. This kit does not come with one because so many people already have them.
The SCT X4 is the most popular tuner out there. There isn’t much to say about it really. Like a key is to a lock, the SCT X4 is to tuning.
This will not come pre-loaded with a tune for your kit. You will need to get that from your tuner.
