More chance that it is for an ecotec... the m62 is the supercharger on the cobalt ss the one for the 2.4 is the m45... And for the tuning get someone that has a hptuner to tune it... the part that you want to zip tie open if you have it installed and not programmed is the boost bypass solenoid that is located on the supercharger, it is the black vacuum actuator...
