The Banks Derringer Tuner for the L5P Duramax adds power and performance to your truck. With the Derringer tuner installed, you'll gain up to 150 horsepower and 300 pound-feet of torque. The Derringer improves throttle response and acceleration. Your Duramax will feel much more responsive, especially at lower RPMs.

Does the Derringer void my warranty? The Derringer is an inline tuner. It does not alter the truck's ECM in any way, unlike a flash tuner that permanently alters the truck's ECM.

Since installing the Banks Derringer I have been asked by many about the fuel economy. The Derringer does optimize the air fuel ratio compared to stock. The Derringer runs at 19:1 while stock runs at 18:1. If I drive my truck “normal” I have seen up to 2 miles per gallon (MPG) increase on Level 3.

It can add 5-50 horsepower to most cars. Moreover, actual torque will be improved simultaneously.

Thanks to the Magnuson Moss Warranty Act, automakers can't automatically void your warranty if you decide to use aftermarket (instead of manufacturer-installed) parts on your vehicle. However, should those parts cause a mechanical issue, the automaker could hold you responsible and refuse to pay for the repairs.

Let's put it in perspective, the Banks Derringer for the 2020 Duramax add 81 horsepower, doubling Stealth's actual gain. Derringer is also connected via OBD and closely monitors the engine and transmission, while the Stealth has no idea what it's doing to the engine, transmission, EGTs, coolant temp, etc.

Because ECU tuning requires adjustment to the factory settings of the ECU, or completely uploading a new map into the ECU, it will void its warranty. The same goes for insurance, however, some insurance companies allow you to specify modifications to the vehicle, which may cover the ECU tune.

Monster Exhaust Systems also include polished stainless steel tailpipe tips. Some models even include a double-wall stainless steel tip to protect it from discoloring from exhaust heat. According to Banks, its Monster Exhaust Systems typically add from 8-14 rear-wheel horsepower when installed on stock vehicles.

It'll depend on the type of tuner and whether or not your truck has a gas or diesel engine, but in general, most tuners will give you about 15 to 50 more horsepower, and up to 30 more pound-feet of torque.

Tuners and programmers improve your pickup's performance by modifying pre-set parameters of the factory computer, such as ignition timing, fuel rail pressure, injector pulse, air/fuel mixture, and more. In turn, the engine runs more efficiently, thus increasing power and fuel economy.

How much HP does a pro tune add? ›

We have seen gains of 20+ hp and tq with a protune over the OTS maps. This is because we keep the OTS maps on the conservative side of the spectrum while our ProTuners are able to push each individual car a little further for more performance. The Stage 1 tune will wake the car up.
