Widmer isn't a scam artist, he sells decent products. He is a smoke and mirrors artist, claiming knowledge and experience he doesn't have. You want to buy parts from him? He cuts people a good deal if they buy from him regularly, and I've no experience with his china heads but I've never seen one of his Wiseco's fail and other tuners speak well of them.
Bisi isn't all he's cracked up to be and it's obvious when I directly asked him on HT about why some turbo Y8 setups are so damn volatile and he had no idea what I was talking about. He has run with the hype associated with his name and not been fully honest. Whether or not he's a full scam artist or not I don't know, but he has sold parts that don't fit then talked to the shop owners doing the install like they are dogs, he has sold untested cams that didn't make any power gains on an otherwise pimp setup, and there is pushback starting to pop up on forums where people are less than happy with his products. Some are on this forum and definitely not n00bs or strangers.
Do you think I'm being unfair?
