"it made a difference i used to CAI 91 octane program. Ive never used one of these before so it was a little intimidating. when i had it hooked up to my computer i did the demo and had to call diablosport and unmarry it. so i was able to redo it to my car...Also im learning as i go how to change different paremeters..since i use about 6 gallons a gas a day driving back and forth to work. i want to try out the gas milage setting,s." —Roger B from Mount Vernon, WA bought a DiabloSport Trinity T-1000 Programmer for a 2007 Chrysler 300, 5.7L Hemi.

Thanks." —Joe C from Sutton, MA bought a DiabloSport PC Interface - USB Cable Kit for a 2007 Chrysler 300.
