I have a 2012 Chevy 2500 hd. I had a 2010 and bought the flashpaq programmer and never had any issues. I got the new 2012 and updated the programmer and when i try to enter the prgramming mode, "service traction control" comes up in the info center and the programmer shuts down... any ideas as to why this is happening?

 

I would give them a call

 

sell it and get a tune. or if you want to keep it, call customer service
