Hey Trott.. Thanks for asking about the programmers...I do have the DiabloSport and the SCT tuners.. Both are like new and basically are... The DiabloSport Predator has a preloaded program for 2010 - 2011 Camaro SS and for even more increases HP custom tunes can also be loaded into the Diablo and installed in your vehicle. The SCT has a preloaded program for Edelbrock Supercharger, but I did verify that custom tunes can be installed into the programmer and loaded in the car as well. Sorry it took me a while to find your message. This is my first posting and I am still learning the ropes. Thanks again and please let me know if you have any other questions.
