Don't have a stopwatch or g-tech of any kind, all I can say is that it absolutely rips off the line, compared to before where it would kinda bog/lag for a while. I'm back from another drive, and it's awesome. Power is available at all speeds, and I had to turn off my trac control because it was lighting up the tires every time I took off around a turn.
