I'm sorry, but I've always wanted to know what are the exact procedures that take place in "dyno tuning" one's engine. Also, how big are the gains (hp/tq) expected to be from "dyno tuning?"
apparently not much (2-5hp), your better off with a chip.
A mail order chip is better than a dyno tune?? Is that what your saying? 
I hope not. Usually a dyno tune involves adjusting most of the engine's parameters for performance including A/F ratio, spark timing, MAF functions, etc. Some tuners will take it further and drive it around on the street to adjust any other issues.
However, some mail order tunes are very good. There have been people on the CEG who have reptorted good gains (10+whp) with mail order tunes.
