Load Based (Dyno Dynamics) vs. Inertia Based (Most DynoJets)

WAAAAY lower than any of out stock motor boosted cars. Either your customers cant drive, or something is wrong..Stop dragging me into your little dyno debates..I proved you wrong last time, dont make me do it again and make you look like the fool you really are..Besides your car and Jason's, what MRC stock block customers have trapped in the 120's? Or even over 115mph? Im curious....
EDIT:
It's pointless to argue back and forth, Regardless you did a nice job on the car, good luck with your future projects.

i liken my car to a girlfriend... i treat her well, spend lots of money on her...and would never allow her to be in the hands of someone i cannot trust...

11's on the stock block....with just 410 measly whp on my dyno. Good stuff!

If your tuner is tuning on an inertia based dyno then they are not tuning your car. At best they are guessing and hoping for the best. I know; I’ve tuned on DynoJet Dynos. I know I was guessing many times when I tuned on those dynos. That is why I always, always confirmed my tune on the street. A DynoJet only provided me a safe place to accelerate the vehicle to triple digits in an efficient time period.
I am not saying a DynoJet is better than a DD. I have been wanting a DD for years, but I would not get rid of our DynoJet either. A tuner can tune on almost any type of dyno. Some just make low speed mapping easier and faster, which I am all for.
The start of this thread to me implies inertia dynos suck, and people who use them are not real tuners. IMO, people who start these kind of threads are just ignorant.

WOW - Jon comments on this thread...
How about some tech info on the FCON V-PRO threads too... 
Now we have performance shops AND manufacturers in the mix... Wow.
I think it's safe to say that everyone agrees that load based dyno tuning is the preferred method, but that in NO WAY does tuning on an inertia based dyno mean that you can't dial in the tune correctly given that the tuner knows what they're doing.
Overall, and all arguements aside, very informative thread.

So let me get this right.
Everyone agrees that a load based dyno is a better tuning tool?
Its a yes or no question. The answer obviously being yes.
So I've become quite confused. Jon, Sam, or Jeremy could you please tell me WHY you would like to have a load based dyno?

You're not getting it. I'm pretty sure they aren't disputing that fact.
From what I gather they're saying that you made some false statements in your original post. For example, the guessing on a dynojet.

Load base dynos also speed up the tuning process - for a business owner, time is money....
I know several experienced tuners that specialize in certain vehicle platforms, and they can create a base map based solely on the vehicle mods and get close to 80% there with out any dyno or road tuning... As mention several times on this thread, experience is key - but the knowledge of learning what, why, and how is the foundation that every tuner must have.
Reading books, attending classes, get certified and finally getting some experience under you belt are the makings of a great tuner!
