I personnally dont like mailorder tunes, I wouldnt use one again if someone paid me too. Your best bet is to get someone in your area to dyno tune it, if your in allens area have him do it if not go through someone else, a dyno tune cost the same as a mailorder tune. If you cant find a dyno, then go with a handheld alot of guys are very happy with thier handhelds and are running better times with them versus mail order tunes.

I dont know why everyone is all over these mailorder tunes like they're the end all be all they are not and in alot of cases all they do is throw in alot of timing and fuel
