I've had the Bully Dog hooked up for about a week and a half now running on the regular tune setting. The setup was a little funny at first. I updated the software as it strongly suggests, which I think initiated the setup wizard. So when I installed it on my truck, I had to manually initialize the setup. No real big deal, but does take a couple minutes. For my '02 Sierra 1500 5.3L, there are a couple fuses you have to pull when you reprogram (so you have to do this if you want to change any settings or program lvl's). The little ATM fuses are kind of a pain to remove, but not terrible. I used a Buss fuse tap (that I ordered when I ordered the Bully Dog unit), and it made it a lot easier to install the remote power line.

As far as performance goes, I definitely noticed a quicker throttle response and a little better acceleration. Again, I only have it on the regular tune, and haven't tried the performance tune. Not sure I want to spend the $4.25 a gal for premium gas at the moment. I partly bought the unit to help with fuel mileage, but haven't seen much of an increase just yet. I do a fair amount of city driving, so it may not really help in that situation. I'll see how it does this weekend on the highway. Hopefully there will be an improvement.

The driving coach is kind of a nice feature to remind you to lay off the gas a little. A little annoying though in traffic when you accelerate or brake and it beeps at you a lot. (There's a lot of idiot drivers here in Buffalo, NY).

The diagnostic feature is quite nice too. It scans for codes, and gives a brief description of the error. I didn't have a check engine light on, but was getting a MAF low voltage error. Pulled the MAF and cleaned it, and cleaned/re-oiled my K&N, and it cleared it right up.

I ordered this Item to install in my 09 Chevy Silverado 5.8. After I lifted it and put aftermarket oversized tires and wheels it obviously had reduced performance. But worse off it had a major reduction in fuel economy!!!! It went from about 16.5 average HWY/CITY down to 12.5. Yikes, with todays fuel prices. I started with a cold air intake that gave me a good boost in power but only about 1 more mpg. Then I put dual catbacks for the exhaust wich made the truck sound great and added a very small power boost but no notice of better fuel economy. I have a lot into this truck and plan on keeping it for a while so I was on always on the hunt for better fuel mileage. I decided to try the Bully Dog 40410 GT Gas Guage Tuner. It was supposed to be for the most part a power performance addition product. But what I noticed more than that is it boosted my fuel economy right back up to stock before wheels and tires!!! And maybe then some. I do notice a slight power increase in the normal tune and have not done the performance tune yet as my main reason for getting this item was fuel mileage increase. I hope this helps. I wish I would have bought this before I already put 10,000 miles on the truck. Do the math, approx 800 gallons of gas used in those miles could have been only 606 gallons. I use Plus gasoline so I spent about $2,500 and could have gotten away with spending only $1,880 if I would have got this thing when I got my tires. It will pay for itself in less than a year!!!!!!!!!!!!! :-) The only reason 4 stars is that it could be a little more user friendly and that it did not add a big noticable amount of power. I would give it 4.5 stars. Very good product!

Bought the BDGT after reading several good reviews on the Titan forum. I installed the tuner as per the instructions and it did what it should until I uploaded a custom tune . It froze at 99% and that was it. After almost three hours and three "techies" who had to defer to their "engineer" for every question they finally told me to have the truck towed to the dealership and that they would take care of it. The last "techie" that I talked to, Shanna, did her best to try to get things resolved but in the end had to defer to her "manager". The service guys at the dealership said that the ECM is "fried". I contacted Bully Dog and they said that they would take care of it. On 01-17-13 I found out that it would be $1200.00 for the repairs and contacted the "manager", Scott Gordon, who told me to fax him a copy of the repair bill and he would talk to his accountant. I asked him when I would hear back from him and he said "after I talk to my accountant". It has been a week since I had the truck towed. Amazon was very gracious about the return and promptly refunded my money. I still await Bully Dogs response...

Have ran about a 1000 miles since getting it. Intalled in a 07 nissan xterra. Was very easy to install just had to go to the auto parts store and get a add a fuse link. The unit has taken me from 14 miles a gallon up to 18-17 miles per gallon. I've also noticed that the truck has more snort snd get up and go, fixed a slight hesitation in acceleration.

So I like it and recommend it to anybody wanting to get more power or gas milage.

would have rated it 5 stars but the display is a little to small, and I fell they should have given the add a fuse with the unit.
