My car has always been faster footbraking from an idle than transbrake off the two step (~3,000 rpm). But mine is a carburated combo. I've always chalked the difference up to all the nasty raw fuel flowing through the manifold, ports and cyls while the throttle was wide open and the car was at only 3,000 rpm coughing and barking on the two step. then when you let the button go there is a period of time where its very rich until all that mess cleans up. Now that I have a logger, sure enough the O2 graphs show this exact thing to be the case.

I suspect the guys with fuel injection don't have the same problem, since when you are on the two step, the program is also limiting fuel as well????
