I would recommend the Compushift system. This will give you the most for your money. You do not need a laptop to program it. The best part about the system is that it comes with everything including a harness that has factory GM plugs. Check out bowlertransmissions.com or give them a call. The system can be purchased with or with out the display. Bowlers will set up the program for your specific vehicle, that way if you don't want to speed the extra $200 for the display/programmer you won't have to.
