I see where some tunes have the tc locked at all times. How does that differ from one that isn't locked at all times?

None are locked in first gear(of course), but typically race tunes have the TC locked from 2nd gear on up. It depends on how you prefer the shifting. I turn the shift firmness up on my race tunes, and that makes the all TC lock strategy a little uncomfortable on the street. If you are serious, get a strong street tune and a race tune, see what you think, and go from there. Once you get to the point where you're running really strong tunes, you'll find traction begins to be a problem.

Will your truck ever see a real dragstrip?

Yes I would like to take mine to the dragstrip..... So firm shift points are for strip and not for daily driving.

Firmer shifts are actually better for the tranny in the long run. Smoother shifts are smooth, because the tranny is slipping.

Ohhhh! I understand now. I just though since it shifted hard that was bad for the tranny. I now understand. Just out of curiosity is it possible to write your own tunes? How is it done?

Just depends on how much money you have to spend for the software setup.

There was one user that liked the Sniper software for tuning, but I don't know much about it. I don't know if SCT will let you buy their software without joining their network of tuners and resellers of their tuning devices. They might, I just don't know.

Biggest thing is the learning curve. Far cheaper to just pay for tunes, instead of hoping you don't screw something up tuning the truck. They may have safe guards to help prevent that though.

I'm also curious about the smart phone hardware, the iTSX I think it is. I'm following this thread too.

I have a Powermax Turbo i used for about a month or two on a stock truck. It would go great on a truck with a tuner. I have it for sale in the classified section. I wanted to feel what it would have done with a tuner but never got the chance.
