On 6s try dropping another tooth or two on the pinion rather than adjusting speed with the epa. Dropping the gearing down will help to lower your current draw and you may get the extra time you need. 6s 3300mah is about 73 watt hours, battery I used last year was 5s 4500mah or about 83 watt hours and I could get about 17 minutes on the track. So you may need to put your truck on a diet and lose some weight or maybe be a little smoother with the throttle.
