Bully Dog GT Diesel Tuner without Pyrometer

Bully Dog GT without Pyrometer. Part # 40420.
A pyrometer is NOT included with this tuner. A pyrometer isn't necessary, but it is strongly recommended that you use a pyrometer for safety defueling and engine protection. Ford 6.4L Power Stroke trucks will use a factory sensor in the manifold to monitor EGT's, but all others will need to already have the correct pyrometer installed, or else the GT Tuner w/ Pyrometer should be used.

The Triple Dog GT (Gauge Tuner) is a vehicle engine tuner, monitor, gauge and diagnostic device all in a single unit. The GT dramatically improves the utility of several vehicle applications by providing an increase in horsepower and torque and by improving fuel economy through better engine tuning. The GT monitors and displays over fifteen different vehicle parameters (PIDs) and it includes our all new Driving Coach feature which teaches end users to maximize their vehicles fuel economy potential. The GT performs vehicle diagnostics by reading and erasing diagnostic trouble codes; this level of vehicle transparency isn't offered by any OEM or by any other aftermarket product. Also included is our performance testing feature designed to test a vehicles performance capability on the drag strip; couple this with our free PC analysis software and users can also determine vehicle horsepower. The GT does it all and it works on most late model diesel pickups including Dodge, Ford and GM. and Yes, its adjustable on The fly!

Improved Fuel Economy: The Perfect justification
So is it really true, will this product give you improved fuel economy? The answer is: heck yes; but only if you drive conservatively. If you have your foot to the floor everywhere you go, you are liable to see a significant decrease in fuel economy. That is why we can’t say for sure how much of an improvement this product will provide because it all comes down to the driver and their individual driving habits. It is true however, that due to the engine tuning process, better fuel efficiency results as a by-product of added horsepower.
