I would have gone with ecutek if someone local still sold them, but since no one does I had to find something else. Plus I like the extra features that the utec offers like multiple maps w/ remote switching. Didn't mastro tune a car with more or less the same set up as billy only he was running a utec and ended up making more power? Im not saying the ecutek isn't a good piece, and I dont think one is miles ahead of the other, in the end it all comes down to who can tune them better
