In a manual transmission, the effect is the same only more pronounced since there is a direct connection between engine and transmission...no slipping torque converter.
I keep thinking about this statement but unfortunately cannot find any information neither for nor against it. From what I have read at different automotive forums "when your foot is off the accelerator injectors do not get any gas"

Hopefully somebody else will chime in...
