More power tuning, simply put, powertune 4×4 cramming more air + fuel into the engine. The more air thrown into the combustion chamber, the bigger the explosion in there and the more power your engine produces. This is accomplished either physically with upgraded hardware (like an air intake or a performance exhaust) or by tweaking your car’s software with a remap.

For the most part, a remap is the more common option for those looking to get more performance out of their car. Rather than replacing or adding a new chip to the engine control unit, remaps change the various tables inside the ECU that dictate how your vehicle operates. Most remaps offer 3 different stages, or tunes, which are typically broken down into the amount of modification each stage makes to your car’s parameters.

The other option for those seeking more power is what is called a piggyback tune, also known as a box tune. These are devices that trick your engine’s sensor outputs to give your engine more power. They do this by “faking” certain sensor data like turbocharger boost pressure, which makes the ECU think that it’s blowing harder, resulting in your engine cranking out more torque.

To get the most out of your BMW, we recommend installing supporting modifications such as a cold air intake or upgraded intercooler and a performance exhaust. Dyno or road-log testing can then be done to optimize your tune and ensure that you’re achieving the most power out of your BMW.
