I bought my Hypertech programer via ebay. It was brand new. AND, thanks to microsoft's cashback deal, I picked it up for $265. 
I have an 08 Sahara, 3.73, sitting on 35's - Plugged it in and programed the JK. I definitely do not have to mash the skinny pedal to get her going now. It is much more responsive. I am going to try the premium setting next time. It took me nearly 30 minutes to program as well. I need to check my speed to see if it is correct.

Don't go by the manufacturer's tire height. lol My mfg says my tires should be 34.4" but I measured them at 33.5" (315/70r17) When I programmed the 34.5" in my speed was way off, but changing it to 33.5 made it exactly right according to my GPS. I might have 34.4" tires if I ran at the 60psi or whatever it says is the max psi, but I run them around 30psi.
