So on my Forza 6 I cant apply a turbo to any of my cars. Anybody know how to fix it.
I don’t think it can be fixed but I can tell you why it happened.
If you apply another player’s setup to your car that uses any aspiration conversion before you have applied it yourself you will never be able to add the conversion yourself after the setup has been removed. In future it is wise to add all aspiration conversions you might use yourself before loading other setups. Sorry but you will have to buy another car.
