It looks like the ECU of this car uses an MAF to meter incoming air. On systems like these, mods that increase airflow (intake, exhaust) should be automatically compensated for.
Of course, the stock tuning is conservative. It will do better with a tune, but visconti's standard tune should take into account mods of this nature without requiring additional logging/tuning.
The one pitfall is that in order to keep the MAF signal to the ECU correct, the diameter of the tubing where the MAF sits must be maintained. If it's sitting in a larger-diameter tube, the MAF will report less airflow to the ecu than is actually flowing. If that's the case, either a tune specific to the intake needs to be flashed or the MAF signal needs to be modified.
Systems like those on Hondas rely on MAP sensors and throttle position to calculate airflow. These systems will not compensate for devices that change the volumetric efficiency of the engine and will need to be tuned for best results.
