Truck Tuner/Programmer Buyers Guide

Here are a few things you should know about truck tuners/programmers in general.

How Performance Programmers Work

There is a built-in computer inside every modern automobile. This computer controls various functions such as the air to fuel ratios, shifting of gears, ignition timing, speedometer calibration, etc. Mostly, the programming that is done inside the cars is convenience-based instead of performance-based. If you want to maximize the performance of your vehicle, you need to attach a programmer and change the settings of your vehicle.

These tuners/programmers change the communication system between your vehicle’s computer and the engine’s various systems. You can tweak the ignition timing, change the speed limits, etc., to maximize and enhance the capabilities of your car’s engine.

Benefits of a Performance Programmer

There are several benefits to buying a performance tuner. You get power gains of almost 0-40 horsepower on gas engines and from 75 to 200 horsepower on diesel engines. The throttle response of the car will be improved, and your gears will shift more easily. You can adjust the speed limits, enhance the fuel efficiency, calibrate the speedometer, and a lot more. Programmers are among the most popular aftermarket upgrades that also include tonneau covers, cold air intakes, and exhaust.

What to Look for When Buying a Programmer

Before you buy a programmer, there are a few things you need to take a look at. They are as follows:

  • Tuning Options

Look for a tuner that offers multiple tuning options. Multiple tuning options include economy tuning, which increases the mileage on a car, tow tuning, which makes it easier for the vehicle to drag heavy loads, performance tuning, and extreme tune.

  • Installation

The programmer should be easy to set up, and should have a friendly interface so that you can easily make the changes without professional help.

  • Error Codes

They should have the ability to read and clear error codes so that you would know beforehand if there is something wrong with your vehicle.

Things to Avoid When Buying a Programmer

There is no good tuner or a bad tuner. You should choose a tuner based on the car you are trying to remap instead of the tuner’s qualities and features. Make sure that there is a big difference before you choose a programmer based on its throttle response, as throttle response can easily be manipulated. Get a stock map graph and compare it with a tuned graph.
