Don't take chances - replacement parts

Bought for my 2010 F350 and after several days of trying to start it somehow damaged the engine. Not sure how bad it is yet but it fought the original fuel management program during the regeneration cycle and kept shutting off the fuel and power mode when the Pryor temp hit 1200 and it takes 1600 for the DPF to clean properly , so there's a constant back and forth battle with fuel I think I overheated the turbo and melted the gasket, causing all the oil from the engine to burn and smoke a lotโ€ฆ

Pros
  • Easy to read control panel
Cons
  • Zero

Waste of $$$ on spare parts

First I did an online update but it didn't install on my 12 RAM 3500. Called BD and they had great customer service but I had to install updates manually. We are camper drivers and pull 17,500 #5th wheel. I've tried different settings but don't see it helping at all. I leave it plugged in all the time to easily change the settings but I just don't see any difference. I bought it to increase fuel economy but haven't noticed a significant difference, I don't see any increase in performance, I'mโ€ฆ

Pros
  • This is great
Cons
  • Speed

I recently switched to diesel and had no idea about the performance potential of diesel engines. I have a 2006 Dodge Ram 2500 with a Cummins 5.9 diesel engine, it's a Rock Stock truck with 85,000 miles on it. Installing the Bully Dog Tuner changed the behavior of a very capable work truck into an 8,000 pound Corvette. I'm amazed at the power and speed the truck has now. I've upped my mileage from 14-16mpg to 17-21mpg, I find it better to keep my foot out of the way. The tuner has fourโ€ฆ

Pros
  • Delivery was very quick
Cons
  • Good but not great

It's over, a huge waste of time and money.

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

Pros
  • Absolute legend
Cons
  • No

Amazing chip performance for days great for the price

So firstly I'm tired of people talking about mpg I want to hear hp. and let me tell you YES, I've liked this thing for days. Let me just say some pros and cons. Pros: It works, it adds tons of power, the small size doesn't bother you while driving, lots of options to change things, adds LOTS of sensors, and it's easy to see and read. Bullydog's support has been great. Cons (IMO) Installation sucks just because it's slow. I have a 2003 Chevy Duramax 6.6lb 7. Due to the age I had to contactโ€ฆ

Pros
  • GOLS certified
Cons
