Most likley not, any dealer (
http://www.sctflash.com/main.php) should have the units in stock. Just find your (BEST, ask around!) local shop, call and make an apointment for a dyno tune and tell them you need the tuner itself...
They have base tunes in a computer they put in your tuner and in your car. Often then they hook it up on the dyno, start it and check the perimeters idling... if all looks good they do a low power pull, kinda like grandma, going through the gears at low RPM while they look at the numbers, mostly air / fuel. If all looks good s/he might get on it in fourth still with a close eye on the A/F... After this you'll prolly have some more power... now s/he should do some small adjustments (on a computer screen) then load that tune into your tuner and then the car... depending how complex your car/tune is and how good/willing to work your tuner is this might happend a few times. Not all runs will be better as a good tuner play around and change stuff to the extremes, like timing etc. They'll that way see what works, and what doesn't...
They do have SCTs base tunes in the computer, they might also have tunes they made 'for fun' or tunes from other similar cars. My car has some 100 dyno runs that are all logged and stored (at MD) to see what different settings do. There is also tunes for CAI, CMDP, X-pipe, UD Puleys, stand alone and in different combos... This way Ken can see what he changed for best power let's say adding CMDPs to an allready CAIed car... of course all cars and set ups are slightly different and needs fine tuning (hence professional cutome tune!) but they'll have a place to start... But they must have a fresh/clean tuner unit that needs to be assigned to your car before they can start, that's how SCT make their money...
Now go find YOUR tuner on SCTs website!
Good luck and have fun! A good relationship with your tuner is a great and valuable thing to have, for your first tune and for comming ones!
PS. Don't get that other brand! :winks
