Diablo sport or superchips? They both seem ok... anyone?

BULLYDOG is the way to go.

Is it diesel or gas? If it's a diesel, the Smarty programmer hands down.

yes the smarty chip i have to love it

Is it an early 04 or an 04.5? I hear the Smarty is better on the later common rails (04.5+) but not necessarily on the 03-04 trucks. I think i've read that Bully Dog or Edge is pretty good on the 03-04 trucks? I have an 06 with a Smarty and I like it.

Edge juice with attitude. Great product.

The smarty is ok i have it on my truck now. But hands down if you want to make power the Edge juice with attitude is the way to go. the smarty works good but it sucks, you can not change your power as you drive you have to stop shut the truck off and re load every thing. Takes like 10 min. the Edge juice with attitude just push the button as you drive.. and rool some coal... if you have any ??? just ask.

I have to slightly disagree. I don't think the Edge is better for making power. The most you can get out of the Edge is 160 hp and you have to pay an extra $100 to get to that level with the hot unlock. My Smarty makes up to an extra 230 hp and it has more adjust-ability. I do agree that it is a big pain to stop and turn the truck off to reload levels and the edge is just a push of the button on the fly, but if you want power go Smarty. If you want a great overall package but huge HP isn't your main concern, go Edge. I've had both so this is from experience. As for which of the two you mentioned is better? I have no experience with those but I think you will be happy with either. Anything will make these trucks come alive.

How are you getting 230hp out of your smarty?

Here is the paper work right out of my box.

Here is my 01 with the edge.
