I'm picking up a barely used Trinity tomorrow for $400 from someone tight on money. I just want to make sure that i'm not missing something. he says that it's unmarried from the vehicle that it was on and has not been registered yet. My SRT8 jeep just has a mopar CAI and Billy Boat exhaust on it. What should i look for when inspecting this. are there different versions of the trinity model? he purchased it new this year in may, used it for 2 months and has everything included with the unit. Any info would greatly be appreciated, this is my first diablo sport tuner. Thanks guys. I just want to make sure im not getting excited about a model that's been revised and pulled off the shelf for something crazy lol. seemed like an awesome deal and didn't want to pass it up. What should i look out for when inspecting this and the package? any specific info to look for? manufacture date, options, features, etc.?
