PMS OR TWEECER R/T ???

I have only used the TwEECer RT and it is not that hard to use, and I have never done anything like it before. There are so many places on the web that have people just like you and me that don't know where to start, but luckily there are a ton of people that do know what they are doing and all you have to do is ask them questions. Just gotta start somewhere
www.eectuning.org
www.mustangworks.com/articles/electronics/
www.moates.net/fileman/index.php?dir=1 (this has all the base maps you would ever need to get started)

shouldn't be too hard to figure out which one you want, i think the approiate question would be tweecer or aem EMS, thats seems to be on my mind though if i was in the position. tweecer seems to have ton of info while ive seen some info on the EMS i havent heard much about self tunning with the EMS
