Review the Best Porsche Performance Chip Tuning Box Kits to Buy Right Now

This article explores the best chip tuning box kits (also known as “piggyback tuners”) to unleash the hidden potential of your Porsche. Because if there’s one thing we know about that famous German engineering, it’s that they’re always pushing the limits of what’s possible on the track.

Performance Chip Tuning Box Kits vs. ECU Tuning and Reflashing

Tuning box kits are not to be confused with ECU tuners. While both serve similar functions, there are some crucial differences that every Porsche owner should understand.

Tuning boxes are plug-and-play kits that fit between the sensors in your car and the ECU and trick the ECU into creating higher output by manipulating the feedback signals from the sensors.

The gist of it is that tuning box kits let you retune your car without actually affecting the ECU and accidentally voiding the warranty. Reflashing your ECU will change the programming of your ECU from its factory settings. While it’s not impossible to return to factory settings, this can potentially make it much harder for you to get trade in your car at a later date.

Moreover, manufacturers these days have gotten very picky about how their new vehicles should be tuned. Many manufacturers—Porsche included—have developed anti-tuning measures that prevent the ECU from being read and overwritten. Any tampering with the ECU will void your power train warranty.

Advantages of a Performance Chip Tuning Box Kit

That’s why tuning box kits are so great: they let you tune the car without ever touching the ECU. Instead, a tuning box works as a kind of middleman in between the ECU and the engine. By catching and modifying signals sent from the engine’s sensors, a tuning box can trick the ECU into thinking that the engine has not yet reached its maximum settings, even when it has.

As such, the ECU will send a signal back to the engine to boost power output or torque. The result is that the engine is pushed beyond its normal factory-set limits.

In this way, a tuning box can achieve similar results to an ECU reflashing, but without reprogramming the ECU at all. It allows for ‘zero detection’ tuning; simply remove the tuning box when you don’t need it anymore and dealers and mechanics will be none the wiser.

“A piggyback tuner is generally a more budget friendly item,” an expert from Flat 6 Motorsports told us, “and it’s easier to remove it off of the car.”

“If you have a new car and you have a flash on it, it’s inconvenient to pull the flash off,” they added. “Realistically, the big difference in performance is that you’ll have more power out of an ECU flash, but with a piggyback tune you can get a boost without messing with the warranty.”

However, it’s also important to note that tuning box kits “produce more latency and lag” than a direct ECU flash. This is because they have to send signals between the engine and the ECU. At higher speeds and power outputs, some experienced drivers may begin to notice a lag.

We’ve talked previously about the essential differences between tuning box kits and reflashing in our previous article on the best ECU tuning box kits.

Be aware that this tuning box kit is designed for turbocharged vehicles only. It does not lock to the vehicle and is installed with OEM-style connectors.

Like all VR Tuned box kits, this is a vehicle-specific plug-and-play kit with several pre-mapped tunings included. It’s been engineered and tested to function in all kinds of extreme environments, temperatures, altitudes, and driving conditions. No matter what driving you’re doing, this kit has a mapping for you.

According to Flat 6 Motorsports, “the VR Tuned boxes are ‘set it and forget it’ and come preloaded with some targets that they want to push. Based off of that, you get a map and it does its best to push the car by forcing more boost. The thing you run into is that, since you’re only pushing the boost function of the car, there’s only do much it can do to create more power.”

In other words, a piggyback can only manipulate one factor, whereas an ECU reflashing can alter all factors of an ECU at once. This, admittedly, does limit the potential of a box tuning kit relative to a full ECU reflash.

Buy directly from Vivid Racing (VR Tuned): $800-$1,500
