Can anyone go into some detail, in laymans terms (haha), what they actually do to a quality built unit, compared to a unit that is not as efficient at the track. Also same question for a street speced converter. And finally, the diff internally between a converter more geared to the track than the street. What is changed internally to change the characteristics. I know the general parts inside and terms. Thanks
