Ya, right, if your working on a dyno, or an idling engine.  Want to seat
under the hood while someone makes a pass at 110MPH?.   EGO, ya fine, ya got
$5K for a good one.  Can't use either in some catagoryies of racing.  Both
have there places, and lots of folks happen to be pretty good reading plugs.
Technology won't replace talent.  Using $$$$ equipment might be handy for a
pro, and a crutch for the lessers, but experience can make up for either.
  It boils down to starting conservatively, and optimizing from there.
Yes, at times I use an ancient Color Tune for working on 1951 MG/TDs.  Just
seems right.....
