Which is better and why? If I tune my car in Florida and drive it to North Dakota will I need to change the tune? Does anyone have any experience with ls2edit that could try to help me understand it better before I buy it? Any help is appreciated.

 

Completely different things, LS1edit is a tuning suite where YOU do the tuning, trifecta is a tunershop that offers in house & mail order tuning where he sends you an interface so you can scan your vehicle and send him data back so that he can fine tune for your application. Too different to really compare as its like apples or oranges.
