The Triple Dog Gauge Tuner has a full-color, customizable screen that lets you monitor up to four different parameters at once. In addition to these parameters, the screen also features a large display that can be customized to show one of three different gauge styles (analog, analog with mini-graph, or full graph) or the Driving Coach display.

Choose from three power levels to custom tune your engine. Note: Damage can result when using the Premium level with engines that do not run on high-octane fuel.

Monitoring Your Engine

The GT tuner lets you monitor more than fifteen different parameters so that you can be aware of the function and performance of your Chevrolet Camaro at all times. Set parameters quickly and easily through the Gauge Setup Menu. Note: Not all of the following are available for all applications.

  • Real-time fuel economy
  • Average fuel economy
  • Trip fuel economy
  • Engine load - no load = 0 percent; maximum load capacity = 100 percent

  • Fuel pressure
  • Manifold absolute pressure

  • Speed (mph or kph)
  • Timing position
  • Intake temperature - at point where OEM sensor is installed within air intake stream
  • Mass airflow (grams/second) - amount of air entering air intake stream
  • Throttle position - idle position = 0 percent; full throttle = 100 percent
  • Fuel level
  • Battery voltage
  • Ambient air temperature
  • Air fuel ratio

You can monitor up to four parameters at a time, with each displayed along the left side of your screen. To view detailed information about any one of those factors, touch the button next to it, and the large gauge area on the right will display the information for that parameter.

Maximize Fuel Economy

Running the Driving Coach program turns your gauge display into an information hub for tracking your fuel economy. Monitoring the information presented here will give you a good indication of how your driving habits affect your fuel economy and overall engine performance.

Bully Dog Driving Coach Display

The Instant Fuel Economy graph shows real-time gas usage. This can be displayed in either miles per gallon or kilometers per liter. The Wasted Energy graph shows your acceleration and deceleration in relation to a base centerline. The centerline represents zero wasted energy. If you accelerate or decelerate too quickly, a color bar will extend out from the centerline, so you can see how much energy that move just cost you.

The Report Card graph indicates your overall engine performance and fuel economy, and it ranges from "A" for optimal performance to "Epic Fail," indicating the need for a tune-up, as well as a change in driving habits.

Bully Dog Driving Coach Report Card

If you're not interested in fuel economy and are really only in this for the extra horsepower and torque, you can remove the Driving Coach from your monitor and instead view a large gauge of any chosen data.

Special Features for Chevy and GM

The Triple Dog GT has several features that are unique to Chevy and GM applications. Adjust shift firmness and shift points to optimize your Chevrolet Camaro's performance. By downloading the transmission firmness feature, you can increase the pressure in your automatic transmission to create more solid-feeling shifting and to help reduce slippage. You can also calibrate your speedometer to correct for tire sizes ranging from 25 inches to 45 inches. The speed limit setting on your Chevrolet Camaro can be raised as well. Note: These features may not be available for all models and years.

Installed my Bully Dog on my 2007 GMC 5.3 and it was pretty simple. This is the first tuner that I have ever purchased and installed. Test drove it and I could immediately feel the extra HP. The only issue I had was with the update manager trying to update the Sims card with the USB adapter, ended up putting Sims card in display and hooking up USB cord and it updated perfectly. e trailer shipping was fast. 237419

I purchased the bully dog gt tuner new for my 2011 Chevy Silverado 5.3 engine,,, I just recently sold the 2011 Silverado and purchased a 2014 Chevy Silverado w5.3 engine,, can I use the same programmer on the new truck without problems to truck or programmer?

comment by: justin r - 01/31/2014


Both the 2011 and 2014 Silverados with 5.3L V8 use the Bully Dog GT number 40415. When a tuner flashes a program onto a truck, that programmer and truck become married. This is to prevent accidentally overwriting the saved stock file that is moved from the truck to the tunner when you first flash the new performance tune. A tuner can only store one stock file at a time. If you returned the 2011 truck back to the stock tune before you sold it then you should be able to use it on the 2014. If you are not sure whether or not you returned to stock, or you know that you did not, you can contact Bully Dog to reset the tuner but there is a fee involved typically to do so.

Review from a similar Bully Dog Triple Dog GT in Performance Chip

I would give this an excellent but the power cord had a loose connection on the positive side, it took a while to figure it out with an ohm meter. I went to Radio Shack and bought a power adapter for a cell phone $17, as I was on the road and had no soldering iron. I am amazed that you can get more power and better fuel economy at the same time. I made the same trip with the same load from Florida to Maine with about a five mpg increase and no need to be in the right hand lane going up the mountains. I am impressed! 82217

  • Bolt On Modifications for a 2014 Chevy Silverado 1500 5.3 liter to Maximize Horsepower
  • As far as products we carry the best option for maximizing the horsepower of your 2014 Chevy Silverado 1500 would be to go with a cat-back system, a cold-air intake, and a programmer. The most bang for your buck that you are going to get for exhaust would be the aFe Mach Force XP Cat-Back Exhaust System with Black Tip # AFE49-44038-B. For a cold air intake that would make the most economical sense and will provide you with just as much power as the other kits I would recommend the...

  • Will Bully Dog Triple Dog GT Gauge Tuner Improve Fuel Economy of 2010 Chevy Silverado
  • The Bully Dog Triple Dog GT Gauge Tuner you mentioned, part # BY40410GMC cannot specifically tune the motor of your Silverado to improve the fuel economy. This being said, a tuner can make the engine run more efficiently, which can lead to small increases in fuel economy. Best case scenario, you'd see a 1 to 1-1/2 mpg improvement.

  • Does the Performance Level of the Bully Dog 40410 Gas Tuner Require 91 Octane
  • You will want to run 91 octane or higher fuel with the Bully Dog Programmer # BY40410GMC if you want to use it on the highest performance setting with your 1999 Chevy GMC Sierra with a 5.3 liter engine. Failure to do so will cause massive engine problems. You will get spark knock/detonation that will eventually destroy the engine. If you can't run 91 octane in your truck you can still run the regular fuel grade tune that will still give you additional power. This tune only requires 85 octane.

Also, if you are asking if you can change the rear end gear ratio with the programmer you cannot. The gear ratio is a physical system.
