Good points. A mail order chip isnt the best way to get performance. Its easy to expand the maps and take off the limiters or change them around, but tuning is another matter. Of course, you could buy the FC for $1500 and still jack it up just as much as a $15 "universal" chip would. If the tuner doesnt know what they're doing, then they dont know what they're doing. No high tech ECU will save a bad tuner
