I have read were you have said that the XCalibrator increase HP 50% friom the 1714 SuperChips tuner for the 04-05 5.4 engines. I am curious is this with each tune (ex. 87, 91, 93 octane)? Are there any dyno graphs showing the comparison of the two? Also I think you custom tune three tunes into the programmer, can that be changed later on if mods are added? If so what kind of pricing will be charged to do that? I think it would be great to show dynos with stock, 1714, and XCalibrator 87,91, and 93 tunes. That way everyone could see the improvements in numbers. I think you guys are on the right track with this thing but I would love to see some numbers before I buy one.
