The Bully Dog BDX and GTX performance tuners offer significant improvements for vehicle performance. This article compares both devices, focusing on their features and benefits to help you choose the best OBDII chip for your needs.
One user upgraded from an SCT X4 to a Bully Dog GTX. While both the BDX and GTX offer cloud-based tune downloads, the GTX boasts a larger, user-friendly touchscreen interface. However, the GTX includes a separate module that requires discreet installation, unlike the all-in-one BDX. This module, roughly 3 inches square, can be attached with Velcro and either left mounted or removed when parked. The magnetic mount allows for easy removal and storage. For long trips or testing new tunes, the GTX is invaluable for monitoring and logging. However, for everyday driving, the device can be detached.
Cost is a significant factor. Bully Dog custom tunes, like the BCB Adaptive Performance and Tow tunes, are available for around $100. The GTX, with pre-installed tunes, costs significantly more at $599. Unless the larger screen and additional features of the GTX are a priority, purchasing tunes for the existing BDX might be more economical. Transferring existing tunes from the BDX to the GTX involves fees from Unleashed Tuning and More Power Tuning. Ultimately, both Bully Dog tuners are excellent products, and the best choice depends on individual needs and budget.
