Chip or SCT?

[01excursion7.3]

So, I'm planning on getting gauges in the next month or so, but I see alot of good talk about the TW chip (hows it compare to the dp chip?), and alot of good talk about the SCT (livewire, is it?) What are the pro's and cons of each? Can they be "stacked"? What does stacked mean anyways, and hows it work?

I'm trying to decide which way is better to go. Current mods in sig, other than that, she should be stock.

Also, I keep seeing mention of valve bodies for the tranny, whats this achieve, or is it just safer to do it? Anyone give me a link to the good ones?

Sorry, newb questions, but I'm still new to the PS/diesel world and learning as I go. Trying to get the most out of her I can, with the lowest cost. I've been told that with power mods, your MPG increases, so give me power!

As far I as I know, and correct me if I'm wrong, but DP is the only company that does CP testing with their programs. Both are great tuners though.

Chips can't be stacked, but are better than programmers!
Chips can switch on the fly, programmers take time to switch in between tunes.

I'm sure there are more, but those are 2 good facts.

chips and tuners can not stack. The tuner will not load into a PCM with a chip in it. Stacking is when you run one computer mod with another, like a Edge juice with a chip. You will not gain much from stacking like that. One guy I know did this and gained 6hp. Another guy I know did this and it gained 9hp. Not worth the money and good tuning(DP or TW) will outperform a stacked combo.

Chips can get into programming areas that the tuners can not get to. Thereby making the chip better for tweakin' 'n peakin'.

The livewire is HUGE. I think it looks like a book standing up on the dash. Again, it is tuned the same as a tuner. Not as good as a chip in the 7.3.

alright, so i'll stay with my original thought and get a chip. Whats CP testing?

What about the tranny's? Anything I can do without rebuilding to make the tranny better?

u dont HAAVE to rebuild ur trany to put the power to the ground.... banks trans command for example is all computer... now other mods like bully dogs trany enhancer... an easy step up... will help hydraulic pressure and eliminate slippige... although a shift kit will probly b the best thing for u if u dont mind dropen a dime.

CP is Cylinder Pressure. You can't go wrong with a DP tuner.
