Interesting news:

"With the release of the 2005 Mustang Custom Tuning has changed. The days of installing a chip are gone, and the new revolution in Custom Tuning has arrived. SCT’s new XCalibrator comes loaded with 3 Custom Calibrations, and retains your factory calibration for quick restoration back to stock."

Gains:
naturally aspirated: 15-25 hp
forced induction: 50-75 hp

Retail price: $375

 

I haven't seen it yet, but then again... I didn't search for it either. That's not a bad deal I suppose if you want to have it in your hot little hands.... but around here you can get a test and tune on a chassis dyno for a third of that, and I'll bet you'll turn out couple more horses... and can see a dyno sheet, too.
nice find, though.

 

How is the dyno shop going to tune your car? They need one of these tools anyhow.

I may get one. I am negotiating with a local dyno shop that is a SuperChips dealer to get the XCalibrator in, and do some before/after with it. So essentially I'll buy the XCalibrator, they will give me a free before/after tune job and dyno sheets so they can get access to the 2005 and advertise it for future customers.

 

You gain ~15rwhp and ~15rwtq with this tune. I emailed a local dealer and he told me "It comes with a programmer and up to 3 tunes." and it is $325 through him, not a bad price imho.

 

not bad at all for the price....
as far as using one of these to tune, I'm sure their dyno equipment has it's own system that can flash the chip....
I guess what I'd want to know is how custom are the 3 settings. I was under the impression that there were 3 choices preloaded onto the XCalibrator.
not all engines run the same and I just figured one could get a better, more specific tune by running it on a dyno. So if you're not going to change the calibration all the time, then I don't see the point in having it except that it's cool to have that in hand.
