Review on 🚀 Bully Dog GT Platinum Diesel Diagnostic and Performance Tuner - 40420 - With 4-Preloaded Tunes by Will Jenkins

Installation went well, although there is no complete documentation. Fortunately, there are several YouTubes that you can link to. My first issue is that sometimes it takes FOREVER to get out of the engine warm-up, which means I'm already where I need to be when it finally happens. My biggest concerns are that I don't see any increase in mileage and that the manual DPF cleaning doesn't work at all, just staying in "waiting for DPF ready" mode. I called tech support several times, they forced me to flash the device even though it was with the latest update, now they supposedly escalated it to "engineering" and they told me there was nothing for at least a week there is to wait . Needless to say, they will return to Revain if they can't make it work. If yes, then I will reevaluate. Not sure if I will try another brand after that as it was the best in all the reviews. I'm thinking about trying the SCT version but I'll see what happens. Not yet worth the €450 I paid. Update: I sent it back. After waiting weeks for the supposed solution to my problem, I gave up. I'm currently trying out Live Wire+ with some custom tunes from 5Star Tuning, so stay tuned for this review soon.
