Most Motecs are like 10grand fully optioned and while they do provide much more versatile. They also cost more and I understand they are not the easiest to tune. A guy named Ara you have probably heard of him has one on his supra and has the motec guys come and work on it for him at the tracks. Which I am sure is expensive. The haltech on the other hand is easy (easier) to tune using bar graphs. It runs like 1145.00 right now which is a bargain compared to the motec hope this helps
