Fuel economy is unchanged during normal driving and the tuning works in conjunction with the DME rather than against it ensuring optimal but more aggressive boost levels with air/fuel ratios and timing to match. Boost is increased 2-4psi on average depending on the climate and conditions. Unlike other N18 piggyback tuners this one actually works and completely transforms the driving experience. This is how the car should have come tuned from the factory.   Literally installs and removes in less than 20 seconds.

See Installation Instructions for JB+ Tune.
