I do appreciate your comment - really I do.
EFILive does have a fantastic support network. For our cases here - it starts with StealthV and extends to dozens or more of V owners. Try the forums at www.efilive.com
Does it cost more?
Does it allow you to do more?
IMHO - yep. I find it somewhat challenging yet intuitive. I've yet to find something that I wanted to do with it (and that I believed would be an actual drivability benefit) that I couldn't. It is some trick software - with a bunch of out of the box thinkers using and designing it. This is not for everybody, however.
Because I prefer Cadillacs over Pontiacs, Heidelbergs over Komoris, and Guiness over Budweiser, it is for me. I'm not wealthy - trust me. I just understand value in a more intimate manner than some others do.
HPTuners makes a fine product. It is fantastic and you will not be disappointed, at least that's what my somewhat limited experience tells me.
Daewoo makes a fine product as well. I use one daily to lift paper from trucks...but I'd never tune my V with it
WW off the beer chest and off to bed...
