I recently was given a Saleen S7 from a friend who rebuilt the engine and refreshed the chassis but it wont let me buy certain upgrades for it such as ECU tuning or any exhaust mods. The car from the factory has 550hp and with the oil change i has 561hp. Does this mean I dont need these upgrades and should just add the upgrades like the Engine mods and Supercharger?
