there is no need to dyno a car unless you just want to see what it puts down...now a custom tune with a dyno session? At about $450 you have to decide if that is worth it to you...
Most of us die hard gear heads want every hp we can get, so a dyno session with a great tuner is money well spent...esp on a built car

^ Agreed.

If someone install a CAI and tune, true duals, ect...you wont want to waste money on a dynotune.
But install those, plus bigger TB, S/C or Turbo and whatever else...you may want to fork out for every lil HP you can
get.

For around $50 to have 2/3 pulls to find out where you are at stock hp/tq wise doesn't sound like a waste to me. Especially if you plan on modding your car, don't you want to see what the mods have done with your hard earned money?

No one is forcing you to spend your money, if you find it foolish don't do it!

Given that even an older used chassis dynamometer goes for around $10K (reference: For Sale Lingenfelters Dyno Jet 248 in ground Chassis Dynomometer - Lingenfelter Performance Engineering Forum), I'd say it's probably not worth it, unless you have a good feel for the market around you.

Serious answer: The only reason to get your car dynoed is because you want to see the effect of individual mods and optimize your performance. They're not good for bragging rights because there's too much individual variation. As you already surmised, the only valid comparisons are on the same dyno (ideally under similar conditions and with the same calibration factors applied).

Yes, dyno the car and for the same amount of money as you would spend on canned e-mail tunes and tuner you can have the car dyno tuned...

I don't speak often but when I do, I don't have clue what I am talking about. I just repeat things that I once heard and do not repeat them correctly... My doctor told me it was an ID 10 T problem and it was incurable.
So when I reply to a post or add to a thread I just find the words elsewhere and copy and paste.

Remember only a fraction of stang owners visit forums. The vast majority couldn't give a hoot about the rwhp of their car. It's good enough stock and leave it alone.

My car spent much of its life strapped to a dyno, obligatory when running high boost (20+ lbs). Still, there wasn't much talk about horsepower numbers and I could only guess my car's rwhp. More focus on air/fuel ratio and such. Too much emphasis on numbers that vary so much between machine types and operators. Notice sigs for cars with low ETs, do not usually include a rwhp # as well, and most that show rwhp #s, don't have low ETs. That's the difference between folk having hp goals and those with ET goals. For most as car goes faster, the hp number matters less.

I wish it were that close. I saw an ad in the 5.0 M&SF that came in the mail today, I can get a SCT tuner from American Muscle with 3 free tunes for $379. At one of my local shops, it's $349 for the tuner + $400 for a custom dyno tune + $125 for each additional tune. If I wanted to achieve the same thing locally as with AM, it'd be $999 + tax. $620 for a few extra HP isn't worth it to some. If you're the hardcore racer, then it is, but for the average enthusiast who wants a few more HP and better shifting, etc...that's a lot.
