Well here is why I say that:
1) Most stock SVTs dyno in the 165ish range. A cat back shouldnt have you too far away from that.
2) Mustang dynos read lower compared to Dynojet (more of a standard around here)
3) Your HP seems too high.
So with that I say its corrected because 175whp on a Mustang dyno would take a lot more than a catback. Also, trying to correct HP numbers across dynos is funky, and shouldnt be done because their is no standard, its just close guesses to what the conversion might be. I think they might have skewed your numbers in trying to give you HP numbers to compare to DynoJet numbers. Either you have a freak or the numbers got skewed somehow.
FWIW, my SVT with intake, headers, catback, etc. (no tuning) put down 175whp on a DynoJet so if you can match that with just a catback, well, I would cry.
And sorry if thats a crappy explanation, Im unable to type much right now b/c my fingers are still numb from having some skin removed from my hand this morning.
We used the same Dyno/shop for our dyno day last year. I'm 99% sure that Mt. Airy Total Performance http://www.totalperf.com/ is NOT adjusting the number as they are VERY anti Dynojet. As far as they are concerned the Dynojet is a Dreamjet that produces inflated numbers. http://www.totalperf.com/dyno.html They could care less about Dynojet numbers, so why convert to false information. They are in the business of building and tuning racecars...not providing false information for show and tell; they use their numbers not false adjusted numbers. What purpose would that serve 
Mike's numbers are very close to my numbers on the same Mustang Dyno he used Dyno-Day link . My pulls were cut short due to my factory rev limiter shutting me down before Max power was achieved. My mods were at the time Bassani Cat-Back, MSDS Headers & Y-pipe, Max-Flow Extrude Honed UIM and K&N RU-3530. Mustang Dyno: 172hp/145ft/lb Not knowing how much more I would have gained I was told there was more to be had based on what they saw.
Yes, Mike's numbers do seem a little high for his mods and compared to my baseline pulls before the headers as well but there have been know to be some freak's out there for sure. So I say excellent numbers Mike...congrats

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?"

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.

Wow this thread has gone bad...Y2kSVT had a dyno tune with his XCAL2. If anyone says a mail order tune is better than a dyno tune...  The HP gains will be diff for everyone dependent on the mods already done for the car. There isn't some magic hp number with a chip.

Couldn't agree with u more!!
Doesn't Y2K have a 3.0? 10 hp yeah and that was not on a mail order chip.
I say on average 8-9 hp on a 2.5 with an aftermarket tune after all the bolt on upgrades. Headers, maf, y-pipe, cat-back exhaust, air intake. That is tuned while on the dyno, mail order i gues a 5hp gain average.
5-6hp gain for a stock upgrade tune.
Mail order is hit or miss. Has been said a million times before.
