afaik the VWR power upgrades are bluefin. i did hear a rumour that VWR were soon to be doing REVO. if they have that id definetaly choose that over bluefin.
how familiar are you with the options for remaps or is this the first you have seen. all i say is dont rush into buying anything until you have done yyour research..
there are alot of guys myself included who bought the first remap they saw, and have then swapped to another remap at more cost. some guys are on their third
