+1 on the Demon! I would go with Neptune instead though, Calvin seems really sketchy with the way he goes about ECtune. I bought my Neptune from HRtuning and it dropped shipped straight from Moates, 100% content with my purchase
:nana: Hondata FTW 
seriusly, both systems have there ups and downs. you just gonna have to do your research and see which one seems more benifical too you.
I will say that this is the “most important” part of any boost build and no expense should be spared while buying a tunning system.
think of it as an investment into a healthy, efficient motor:)
