Talk about allegedly deceptive advertising. Have no clue how much those infomercials cost to run but they must be making buckets of money out of these things. It all sounds plausible but with money spent on R and D all the big manufactures would be paying a license fee to Dr Lee or whatever his name is if they worked to use the concept. I do understand that on carburetered engines they " might " produce a minimal effect but with injected engines, nothing or worse a loss.
Having said all that in the torque tube, I think their called, on CDT's they seem to have a some sort of angled vein in them!
