I am in the last stages of breaking in my new Team Losi GTX and doing a few WOT runs. When it gets to a higher speed, it bogs down. What adjustments do I need to make in my needles for bogging down at WOT?

When I turned it off, i realized the air filter fell off at one point. I don't know if this was before or after I noticed the bogging so I don't konw if that would make any difference.
