Sorry you didn't get the tunes from your dealer - when we sell an XCal 2 we provide a custom CD for all the customers with 3 tunes on it, and a copy of LiveLink. Xtreme Tune, Live Update, the latest firmware and a Custom users manual that I developed for SCT. You can download Xtreme tune to add a couple more degrees of timing - as long as it doesn't ping you are OK - maybe the dealer can email you a file with a bit of timing in it to try??
You can make a number of adjustments with Xtreme tune depending on your EEC Code - but gears, timing and fuel are usually available to all cars, but to do that, your dealer needed to supply you with the tunes.
I could easily supply the tunes to you guys, but since I didn't sell the Xcals I probably should not to step on another dealer's toes.
Hope this helps.
