I can't get more than 310 to save my life.
EDIT: BTW, when you guys are getting low, lights been on for some miles, and you take a right or left turn, or accelerate hard, does your engine kinda die/buck like it's getting fuel starved? I noticed that when i try to push it past 310 miles, if i even get to 310, and I give it some gas, all the power will drop out real hard, car doesn't die, but what I assumed it was was fuel starvation.... goin around a bend hard on empty=intermittent fuel delivery as the pump tries to find the last fuel sloshing around the tank.....
Correct me if im wrong....
