    Ready to pull the trigger on a tuner and mpt tunes. What’s the difference between the x4 and bdx?

    X4 is compatible with more vehicles and is SCT's most popular. It is tried and true. Very little issues with them. The BDX is a newer version of the X4 that allows the tunes to be sent via the Cloud (big help for MAC users) and has some other wifi features along with a better display. However, works with less vehicles and sometimes needs SCT to upload a special file to their server so you can use tunes from aftermarket tuners. Both use the same tunes.
