Todd,
I don't know the difference between a toilet and a terminator, i've never personally run a terminator, but do have a toilet on my 377" and i've messed with a lot of stacks injection units. To me they are easier than a carb to tune, i never mess with the barrel valve after i have it set to what the car likes, either on a stacks or toilet. As you know we can get some 100 degree temperatures here in the south so just changing the pill up or down from the sweet spot is all i ever do. My friends 396" sm/blk runs low 5.60's with a 4.1 toilet @ 2650 lbs. and it's 23 degree head motor. Given my rathers i would run injection over a carb. on alcohol, due the ease of tuning. some people complain about cold starting, i spin the motor over until the oil pressure comes up and if the pump is not mounted higher centerline of the fuel cell, usually the fuel pressue is up by then and it will start easly, if not, give it a shot of gas and the rest of the day it will start just fine without priming.
