I am always skeptical of these claims because they are never done with any kind of rigor. I'm willing to bet that most every DeLorean can benefit from a tuneup - with OEM parts or aftermarket. Seat of the pants evaluations are useless. I would be willing to believe claims if there are documented dyno runs before and after every change, measured against new parts to the original design spec as a baseline. Anything else is marketing. Ever notice how those stupid tornado intake infomercials ALWAYS do a tuneup and filter change on the car with the installation of the part? -- Mike -------------- Original message from "John Hervey" <john@xxxxxxxxxxxxxxxx>: -------------- > > > Dave, > I beg to differ.
