the word NEW. If the car is new you have to break the engine in first before you go down the highway beaking the tires loose at 60mph, not to mention your father doing donuts (By mistake). And one more thing, If the car was tuned with racing gas, you should not have put pump gas in it at the same settings. Octane level must be increased with high boost. Raising the boost raises your compression, and higher compression = higher octane. I hope the damage is minor and it can be repaired but it sounds like you and your father are at fault.
