New from VR Tuned is this performance Tuning Box kit for the BMW M3 M4 F80 F82 chassis with the twin turbo inline 6 cylinder engine. This tuning box kit is a plug and play solution to tune your cars fuel, timing, and boost giving you up to 40% more power and 20% fuel savings. The VR Tuned ECU Tuning Box Kit gives your F80/F82 BMW M car a gain in power from 430bhp to 510bhp gaining you 80hp! Peak torque went from 500nm to 630nm. This puts your M3 M4 in Porsche Turbo territory.

-Plug and Play for easy removal to avoid warranty issues
-Can transfer to your next vehicle, just buy a new harness
-Harness has OEM style connectors, no splicing or cutting
-Tuning Box features an aluminum weatherproof case
-Digital Microprocessor Controlled
-Installs in 5 - 45 minutes depending on vehicle
-Proven power gains
-3 year warranty on parts

With manufactures trying to increase fuel economy by adding forced induction to vehicles that previously had large displacement engines, the ability to tune them further is even more prevalent now. The BMW F Series M3 M4 features the new 3.0L Twin Turbo engine which is well advanced over its predecessor, the E92 | E90. The manufactures have gotten very particular about having their ECUs accessed to be tuned. These "anti tuning" features make it hard to read and write the ECU via the OBDII port.

Engineered for boosted cars, these vehicle specific plug and play kits are designed to easily be installed and uninstalled as needed. The harnesses feature OEM plugs that attach to necessary sensors where the pre-mapped tuning box gives your vehicle huge amount of performance gains. Unlike other "piggyback" solutions, these use high quality connections, wires, and casing that are designed to be engine mounted for longevity to the elements. The actual tuning box is housed in a aluminum casing that is weatherproof. These factory plug and play harnesses allow you to remove the kit as needed for warranty purposes.

Altering sensors related to fuel, timing, and boost, the car is still very safe and reliable as it maintains factory knock control. Each Tuning Box Kit has been engineered and tested to work in even the most extreme environments of altitude, temperature, and driving conditions. If you have any questions in regards to the VR Tuned ECU Tuning Box Kit for the BMW F Series M3 M4.

I'll take early odds of 10 to 1.

Burgur Tuning Piggyback will have much more features than this, make more power, and have more support. And be cheaper!!

I'll pass.

Based on this, I am going to conclude it is a piggyback:

'Unlike other "piggyback" solutions', implying that this is also a piggyback. And looking at the other details, it looks like it plugs inbetween the ECU and the sensors, modifying the sensor input to fool the ECU, which is, by definition, a piggyback.

And this clinches it, yes, it is a piggyback, for better or worse:

If anyone is interested in a "VR Tuned" piggyback, just buy it direct from the source.

I am running this tuning box on another car (CLA250) and while I haven't dynoed it, the gains are quite noticeable.

On the M3/4 we have better tuning options available, IMHO.
