Hope you do well in the race, your mpg's should be better! When you check your mileage again let us know what it did with the red needle. Make sure you keep the fuel line away from the header on the IMS tank. I used some Hi temp spark plug wire covers over my fuel line from NAPA auto parts. I really like the tank but it does hold the heat around the engine. One thing about the tank its bulky size protects the radiators from the sides.
