OK, I have been looking for a tuner, and finally talked to the only local shp with a dyno. Below is his response. My question is, does it make sense? Can I order a tuner empty? Is this a good move?
You can buy the Xcalibrator2 in two versions:
1) Loaded with stock SCT files that the user (you) can change,
2) Empty, the new tune file will be loaded in depending on its behaviour on the dyno (that's me)
I have ALL files for SCT products, I am one of the very few select "exclusive" dealers, I have the latest and the greatest
However I do not recommend "custom tune" files over the phone without the use of a dyno. I call them "teletune" and they can be destructive.
If you don't have any major mods, you can get away with option 1 (I still would recommend a check on the dyno). Otherwise option 2 is the way to go.
