Hi, I've had a search and either I'm half retard or just missed it but I cant seem to find much on the nistune ecu chips? My questions are: are they worth it? How tunable are they? What kind of power do they support? Has anyone had one and had any issues? Any help would be great. If this have been covered already, my apologies.

Some good reading. Page 4 onwards http://www.calaisturbo.com.au/showth...tune+vs&page=4 (http://www.calaisturbo.com.au/showthread.php?t=89262&highlight=nistune+vs&page=4)
