What Tuner is best for me?

If MPT had a leaderboard for the most frequently asked questions, “What tuner should I buy?” would be in the top two—and it might even be number one. With so many options out there, it’s no surprise that picking the right one can feel overwhelming.

Let’s break it down and help you find the perfect tuner for your ride.

What is a Tuner?

A tuner is a handheld performance programmer that optimizes your vehicle's engine and transmission parameters by modifying the factory settings in the ECU (Engine Control Unit). These devices allow you to load custom or preloaded tunes to increase horsepower, improve throttle response, enhance shifting, optimize fuel efficiency, and calibrate for aftermarket parts.

• Programmer
• Tuning Device
• Flasher
• Flash Tool
• Tuning Module
• Calibrator
• Handheld

It’s basically a magic wand for your engine—plug it in, load a tune, and boom: better performance.

Modern vehicles are no longer just machines; they’re rolling supercomputers. They track everything from tire pressure to oil life, so it makes sense that they also control power output, boost levels, and more. Gone are the days of wrenching endlessly to squeeze out extra power—now, you just tell the computer what to do, and you’re off and running.

That’s what a tuner does: it removes factory restrictions and tells your vehicle how to perform at its best.

Choosing the Right Tuner

There are a ton of programmers out there, but let’s focus on the ones that work best with MPT Tunes. Every device on this list is MPT-compatible; the key is finding the one that fits your needs.

Shared Features Across Devices
