I've looked up Haltech, and the thing I don't like is they don't give you as
much detailed information as the MS site gave me.  Kinda leaves me hanging.
Is tuning MS or any of these hard to learn?  I'm not scared to go in and
learn about it, but could I ruin my engine by not using this program
correctly?  Would I be able to upload someone elses map to get me a started
then tune it from there?  Will MS tell you when you need to change your
settings, or do you just change them based on the information that you get
back from you're sensors?

      In your opinion, which one do think is better overall?  It seems like
MS would be, but does Haltech have any big advantages?

    Again, I checked these guys out too, and they don't really get into huge
detail like MS does.  From what I gather it just measures your A/F mixture
throughout you're rpms. Is that correct?
