Bully Dog 40417 GT Platinum Tuner for Gas Applications

In addition to this site, I've read reviews on at least 10 other web sites that claim mileage improvements As part of a K&N system, I installed this In hopes of getting the maximum benefit from the combination, we have put together our own N-Air kit. A defective Micro SD card was the first problem. We had to replace it. In order to avoid waiting for one to arrive, I searched high and low for one that would meet their specs, but was unable to find one that would work. Our next stop is the US Postal Service. In a few minutes, their tech support had sent me one, but not until the weekend was over in light of how unreachable it is on weekends, when shade tree guys like me generally have the time to deal with these types Despite being scheduled for a couple of hours, the installation ended up taking a week and a half. There was a problem, to be sure, they sent me the codes for the previous model year. . . I was told, it is fine, it will work. . . but the ominous warning on the hard to read screen predicts doom if the installation is unsuccessful. I will not press you. Get it installed, download the tune, crank it nervously and . . . it starts up! The lights are not yellow and there is no strange noise. It appears that all is Currently months into ownership, we have varied driving conditions, fuel suppliers, weather conditions and thousands of miles (about 5,000 miles or so) and there has been no improvement in mileage or noticeable power increase (even though the promised numbers are low enough, I am not sure how anyone could know). There is now a several hundred dollar irritating chirp on my console that tells me when I brake too hard, accelerate too hard, and sometimes simply chirps for no apparent reason. I know it has improved my gas mileage by reducing the weight of the cash in my wallet, but it certainly has not improved it Now that it has been disconnected, I will neatly store it in a box on the garage shelf. Eventually, I will forget it is there until it eventually finds a new home in my On the bright side, I can theoretically set the length of time my lights stay on when the truck is off (I believe). A quick update I have noticed an improvement in my fuel mileage since removing the tuner one week ago! No, not by a long shot. I had been getting 5 mpg, but again it has gone up, now I am getting 16 mpg. My fuel economy has increased by approximately 5 miles per gallon, and I no longer have to listen to chirping. The other upside has been that I was able to reclaim my cupholder spot I have one more update to share When the unit is removed and three tanks of gas are burned with mixed driving, the mileage is increased by two major miles per gallon. There is just one more thing to do recover the space on the shelf in the garage where it is stored.

You should be cautious when buying 2015 and later Sierra trucks. There have been lots of problems with this product, which is why Tech Support admitted to that it does nothing. This does not alter active fuel management, driving stability, or traction control, or throttle response Not a thing! Instead of losing money on a throttle commander, you'd be better off saving it. If it has everything it claims, then it will make your truck more responsive. My opinion on this product is that it is purely a Despite the fact that their product works wonders for diesel trucks, it is no good for gasoline They do not have a good tech support department. Not good to leave a lot of messages and not receive a reply. There were 39 people on the waiting list when I was on it which tells me the new products are in need of improvement.

The unit is installed on a 2006 Chevy 1500HD SS with 140K miles. Worked as designed and was promised, exceeded expectations when towing. With high performance mode and only about I did not see that much of a gain in power. The increase in fuel economy is 6 mpg. I did not like the shifting in performance mode, since I already had cold air, true headers and a free flowing glass pack exhaust. I had my transmission set up using shift kits, a converter, and added clutches for towing so I thought it would be okay. I have increased my fuel efficiency from 6. 9 to 6. 9 when I operate a 30' travel trailer running at still 75 mph while in tow mode and stock shifting. In the 5-10 range. A fuel economy of one Due to the fact that I do not want to drive 55, I would never have thought about jumping so high. As well as the engine temperature, the transmission temperature dropped from 205 to 195. To pre-register, click here You should load on rolling hills at the bottom and not wait on the cruise, it usually does not even downshift before rolling hills. A negative may have to be mentioned. I would love to have a kit or replace the fuses with switches if there were one. It is not easy for me to remove all eight fuses that have to be removed during the reprogram process under the hood and inside exactly where they are located.

There were a couple of points I would like to clarify. Below is an overview of how it went for me over three days. When I later tried to download the codes to the SIM card and insert it into the unit, it started throwing me errors about being unable to read the card. I called tech support to find that the files were missing, and they needed to remotely control my computer with the sim I granted him access to Team Viewer, and he downloaded the files from a completely different location. Additionally, he guided me through the installation process (very helpful, but clearly flustered and frustrated by his technical support position, which was evident in his tone of voice). To get an idea of how much my mileage would increase, I set up everything in my car and went for a 240 mile drive. I got a 9- on the unit I am now getting ten miles per gallon, where I was accustomed to Assuming there was an error in either the reading or tire size, I made this assumption. Once I got back to my car, I topped off my tank and measured GREENWOOD, Texas (March 17, 2013) - I divided mileage by gallons used (hadn't used either trip reading, as they weren't correct on either one). There were 11 miles on my trip. Since it was a Saturday, I had to wait until Monday before getting in touch with Bully Dog. Asked them about my findings and that the unit was again saying it couldn't read the sim card. He said either it was a bad sim card or a bad unit, but I had no time to wait for a replacement in the hopes the next would actually work. My first step was to remove the unit, which is supposed to restore factory settings to the vehicle as downloaded from the sim card (maybe in this case). I then Considering that I returned my computer to the factory, you would think I would switch to 15 again. The exact same driving habits decrease my mileage by 1 mpg while the same driving habits increase it. The fuel economy is five miles per gallon. My friend and I plan on bringing it into his shop next week so that he can either send it back to the factory or update the There was a strong desire in me to have this unit work, but I was disappointed. In the shop, there is one of the best ODBII commercial readers (about $8,500), and he said the Bully Dog left the computer in a locked state, preventing him from pushing any It would be terrific if I could get Bully Dog to assist me in getting back to the factory state as it was before installing their devices and tools. I am looking forward to his report.
