That may be true,but if this guy is trying to sell these units,a disclaimer(and I strongly advise he uses one)that states that it won't give mpg gains of 40% on most vehicles will scare away most customers.I know I'd be very leary to purchase one if that was a stipulation I had to agree upon buying that system.
