The game will not let me add on the centrifugal supercharger. When I select the part it makes the noise but doesnt change the P.I or change to the wrench icon. Any ideas. I have already purchaced the supercharger.
You have to purchase the car again. Once an aspiration conversion was used in a locked tune theres a glitch not allowing it to be reinstalled. Purchase Aspiration conversions prior to applying locked tunes to prevent this.
Dang it man! I already have 2! I only unlocked the tune on one of them. Thanks for the info.
