More likely its to do with air pressure and temperature. When you use your car normally it spends about 10 minutes warming up (running richer than it wants). On a long journey it's already warmed up most of the time, even if you stop for a lager break.
Lately we've had good weather for engines too.. Not too hot (thin air) not too cold (takes longer to warm up). Your beast was getting a nice dense air charge (better combustion) and more power for the same amount of gas (so you would be using less throttle than you thought).
Motors run most efficient at 2/3 of maximum revs, is what I've understood (peak torque).
No bullets for Chaingun..
