1515 2Y on 6S???

You are keeping the same total energy in batts, so you cannot expect a big % gain in runtime on such a swap (considering the 1Y is quite eff in the first place.)

To increase runtime, you will have to increase batt size (and weight.) The energy has to come from somewhere. You may get a min or so at most, but can be easily negated by driving style or pile up of mud/dirt on the car.

I figured the gain would come in the form of alot less amp draw.

If you double the voltage and retain the same overall vehicle and motor speed the amp draw will half. But seeing that you have not changed your overall battery capacity, just reconfigured it, you will not notice much benefit. You may pick up a little runtime, and the motor may run a bit cooler seeing you have halved the current passing thru it. Plus you will stress the esc less, and you could go to smaller wires to save some weight (not really worth it IMO.).
