The majority of tuning boxes on the market today will only increase the fuel pressure and injection periods. You will not get an even spread of power due to the delay in the tuning box circuitry processing sensor signals. This results in spikes in the power. With re-mapping, these problems are eliminated as the ECU processes everything along with adjusting the torque limiters and turbo limiters, which a tuning box cannot access.
