You think I'm excited now... I was blown away with how much power the XZT makes! All I hear about is how crazy the truck will run with a smarty on it. Besides, I'm still under warrenty so the Smarty just seems like the best way to go.

Sorry to disagree, but 4.3 is definitely not towing and mileage... WILD TM = very sensitive throttle and not too good for towing. Way too much smoke for towing too.
4.4 was originally billed by someone for towing and mileage-- but it gives too much power for that as well... I do agree it is all around goodness though...

4.4 was next, felt a touch stronger than the 4.3....but was WAYYY too light on the street.
4.2 is raunchy, and now that I stack pressure on top of it.....well lets just say that it makes the standard smarty feel like I left it on #1....LOL

The other settings are not much different, supposedly only how that power is delivered. Every truck seems to respond to the programs differently too... Some trucks dyno sw9 lower than sw3 for instance... fuel delivery and capability has a lot to do with that. Meaning folks with aftermarket lift pumps and modded cp3s can fully utilize the sw's better. In my truck, I feel little, if any, difference between sw5 and sw9.

Quick question. Does it hurt to drain the rail on a stock truck? Example, my truck is stock except muff delete and CAI. And of course the Smarty. So i'm sure running hard on Sw9 will drain the rail right? Does this hurt the motor or just doesn't get enough fuel there for you don't see all the potenial...?

not completely true. draining the rail, drops the pressure to the injectors, giving a poor spray pattern. that will dramatically raise cylinder temp. which in turn melts pistons. you dont really want to go low enough in the rail pressure to experience "popping"

i dont think you could drain the rail with the smarty alone. you'd need aftermarket injectors to do that.
you will however drain your input pressure (at the CP3 inlet) to 0psi if you only have the stock lift pump and are heavy on the throttle. this is bad if done repeatedly as it will cause lubrication issues in your fuel starved cp3.
