I personally have Cobb and love it. I have heard good things from JB4 as well. I just don't see the point in turning it on and off.
I actualy forgot about the learning part of the chip. I have been turning it off because I didn't want to put any more stress on the turbos when I didn't need it. But, I just signed an after market warranty contract yesterday so I may aswell leave it on all the time. except when something fails and it needs service
