It comes with a control box, sort of like a piggyback computer..what it does is tap into the TPS and detects when to activate the blower, ie. 40% throttle the blower starts boosting. You have to modify the fuel pump to. The standard ECU detects more air volume and corrects the mixture automatically..more air, more fuel, hense the fuel pump mod.
No tuning involved at all :)
