Help! Installed Bullydog GT tuner this afternoon. Update went fine. Installation went fine.Download seemed to go fine. Selected Reg/tow and when I started the Jeep it idled rough and then would stall. Each subsequent start resulted in an immediate stall. Did the same thing with the offroad tune. Went back to stock setting and everything seems ok. Called tech support and was told the engineer I needed to talk to had already left for the weekend. Anyone got any ideas?
Edit: This is a used unit I bought from a forum member

 

Dude i would call monday morning and wouldnt stop untill someone fixed it. I have the same set up but mine did just fine no problems. I dont know much about them sorry i couldnt help.
