I was just wondering if anyone has ever used Thunder Products - U.F.O.(Ultimate Flow Optimizer) in there carbs before? Here is a link to there site. http://www.thunderproducts.com/u_f_o.htm At $70 to maybe gain a few HP would it be worth the cost?

They show them pre-cut for 3.5 cutaway. What's yours?

The 6 HP claim from those inserts. Not that easy no way no how. Too good to be true. I think Griz gave them a thumbs down.

Omyyesindeedy, scabber! RMS, if you can't sniff the Thunder Products ads and smell the snake oil, consider the implications of a one-size-fits-all slide cutaway specified by a snowmobile shop in a 4-stroke application.
