Try some 93 octane fuel. Thats about the cheapest upgrade you can make. :D From there its all uphill. !! I agree with the others. Exhaust first !! Then the race is on for the rest. Good Luck, and welcome aboard!! :drink:

Leave the engines stock unless you are ready to spend 5k each. Mybe add K&N breathers.
Best bang for the buck is to get your props labbed. For $300 a prop, you will see 1-3 mph gains most likely.
