Oh yeah, there's a lot more punch on the bottom end with the Smarty. When I first plugged it in, it took some getting used to cause you can feel it pull hard instantly. But I really noticed it the first time I went back to stock and drove it after having it on for a few days, felt like someone had swapped my injectors back or unplugged the Comp.
Still working on the cruise though. I was hoping to find a way to ease it back some so I could still use it, but on #6 and 1x1, it's still surges some on the hills. Haven't played with anything lower than #6 yet. #8 (and #9 when the Comp is off) is really amazing. You can get up and going like you wouldn't believe.
If you want to try it out sometime, shoot me a PM and we can load it up one weekend when I'm down in Giddings.
