Bully Dog BDX Tuner Reviews


Better throttle response and better shift points.

Reviewed By Matthew B (San Diego, CA) Reviewed for a 2015 Toyota Tundra —4/18/2018 8:08 PM

I set the tuner for Towing, turned off the seatbelt chime and disabled the speed limiter. I am pleased with the much better throttle response and,after towing my travel trailer for a couple of hours, noticed better placed shifting while going up hills. Overall, I am happy with the tuner.
