Hi guys, first, I don't know anything about tuning a Corvette and just trying to get more information so I can make an informed decision.
I know that Dyno Pak or whatever it is called. You would remove the tires in the back and then bolt the instrument where your wheels were located. Then the Dyno would take the rear HP reading and tuning by allow the computer to load your rear wheel. I have heard that it is the best way to tune a car and is much better than a DynoJet or Mustang since the tuner can put load on the rear wheel.
The other choice is to have the tuner actually tune the car on a drag strip. The tuner would make a run down the track, get the read out and then tune according to what he sees.
My question is, which of the 2 tuning would be better? I have heard positive on each of the tuning and would just like to get other opinions please. Thanks
A mustang dyno can load the car and a dynojet can be upgraded to be able to load the car. I like to tune on a dyno and then go out on the street and verify everything and adjust if needed. Turbo cars require a little more street tuning than the others.

Ideally, I'd prefer both.
But if I had to pick just one I would choose to be fully tuned on a dyno by an expert.

All chassis dynos load the engine and there are two ways to do it...inertia and absorption. Inertia loading is accomplished by a large roller of known inertia that the engine has to overcome. Absorption loading is accomplished by an eddy current electric circuit or hydraulic circuit that "absorbs" the HP and dissipates it as heat. You can have inertia only (Dynojet), inertia and absorption (Mustang, optional on Dynojet, and a few others I can't remember), or absorption only (Dynopack).
The best for tuning are the ones with absorption loading as you can control the RPM sweep needed for tuning. If you have a Dynojet with a large enough roller and your engine doesn't make huge HP, an inertia only can be used for tuning also. They all have their advantages and disadvantages.

I see this very often on forums and it is total BS. As I said above, all dynos load the engine. Having said that, the Dynopack will be more than sufficient for tuning your car. Any Mustang will too and the right Dynojet also. But one thing you should know, any HP reading from a Mustang or Dynopack will have large errors in comparison to the Dynojet. Don't get hung up on the numbers (they're all over the place) and don't try to equate it to flywheel HP (it's impossible). Get a good safe tune and enjoy the ride.
