This car is an expensive to maintain as any other car, the maintenance fundamentals are the same.
Regarding your second question, when the car is tuned/dynotuned for a specific type or grade of gas, the settings are saved as a tune file. This process can be performed to optimize performance based on any changes made to the engine, exhaust system, gas, etc. Flashing the tune means loading a different tuning file or "map" into the ECU. Currently the car is running a 91 pump gas tune, allowing it to pass smog as the rear O2 sensor needs to be read in order to pass. If you're fine with sticking to 91, you can leave the car alone and enjoy the car as-is. If you want to take advantage of E85/flex fuel and the extra power that it can unlock, the car will need to be flashed with the flex fuel tune before filling up with an ethanol-based fuel. In this case, flashing the ECU is done by essentially uploading the optimized tune file into the ECU using an Ecutek computer/cable interface.
