Hey Chris has the setup gauge ever been wrong that you have to add or subtract more then the gauge was telling you to get the perfect contact pattern?

Very rarely. Out of all the ones I've done with the correct factory tooling (GM, Ford, Chrysler) I can only remember a couple times the pattern needed an additional correction.
