i personally don't think vortec needed to conduct this study they are mainstream already!!! there only competitor is tunze, why did they do it no clue...... they don't need the buisness there not hurting they stand behind there product just as much as roger does, i have dealt with with them in the past....them funding it has nothing to do with swaying the results one way or another if it did tunze would not have released a statement...for one i love vortec and always will i recommend both companies fwiw but i personally go with vortec just for the technology and the number 1 reason looks!!!!!! this study is not gonna damper sells of either company imho....
