Although many enthusiasts claim the Miata to be the ultimate car for both novice and experienced enthusiasts, there are many people want more power and more comfort than the Miata can offer. The BMW Z4 is the perfect solution for these people. The top of the line Z4M is less of a Miata alternative and more of an M3 alternative, as it uses the same S54 engine from the E46 M3. Outputting 330+ horsepower, the Z4M is a fast car, but BMW left some performance on the table to improve reliability and longevity across regions with less than ideal fuel quality.
The engine relies on a computer to tell it what to do. Everything from fueling, ignition timing, speed limiters, and much more relies on the engine computer. This means if you can tell the computer to change what all the components are doing, you can squeeze more power out of the engine. This is the idea behind tuning. Our VR Tuned ECU flash, in particular, changes ECU parameters such as target air/fuel ratio, target ignition timing, and many more parameters. The result is 361 horsepower and 280 ft-lbs of torque, a huge jump in power for a naturally aspirated engine.
On top of the jump in power, fuel economy and throttle response are also greatly improved!

How does the flash unit work if I were to add a charger later?
The tune is designed to work with a stock or lightly modified application. If you introduced forced induction to the vehicle, you would want a tune file designed for boost.
