SCT X4 Tuner
If you don’t already have a hand held tuner you’re going to need one. The GT450-450HP does not come included 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 GT450-450HP kit. You will need to get that from your tuner. Arguably the best 3v tuner on the planet does most of the tuning on our kits. We can put you in touch with him for remote tuning.
AEM Wideband Sensor/Controller (no gauge)
If you are remote tuning your car with a tuner you will need a wideband sensor/controller to measure the air/fuel ratio of the motor. We have had our best success with the AEM units.
This particular unit does not come with a gauge (display). It is intended to wire into your tuning device directly. You will be able to display it with that and data log your air fuel ratio for your tuner. This is a nice way to get the information you need and not have to mess with mounting a gauge(s).
One thing of note. Wideband gauges (on your dash) are constantly fluctuating all over the place when you drive. These drive us crazy. They’re quite distracting. Considering that your wideband reading is 99% for tuning or troubleshooting purposes we don’t run wideband gauges on our cars. We do run sensors so we can see them on our tuner and/or log data when driving though.
