DynoJet or DynaPack?
I am gonna be getting my car retuned here in a little while once I move up there and I was wondering if anyone has some insight (and opinions) about which they prefer: the traditional roller DynoJet or the chassis DynaPack? I've always gone on the roller dyno, I wouldn't mind trying out the dynapack as long as it yeilds good tuning results, not too concerned with the fact that they read lower than DynoJets long as I get a good increase from baseline.
So let me know what your experiences with either (or if you've used both) were and how your increases on each differed from first run to after tuning.

Doesn't matter. Number on any machine are only as repeatable as the person running the machine.

Dynojet + Dynapack = Jet pack?

Well the only place I know of with a dynapack around here is ECS and I know a few people who went there and are very happy with their results. I went to get tuned on a dynojet because that is what TTP uses and their tunes were only $250 compared to $450+(I dont remember the exact cost) at ECS. I am happy with my TTP tune at half the cost. It all comes down to how much money you want to spend.

FWIW ECS charged me 450 for a cam tune, I believe the bolt on tunes are significantly less... Regardless, I had heard that the dynapack was better for tuning purposes. When ECS tuned my car they did a street tune anyhow (this was back when they had a dynojet).

Thanks for the inputs so far. Yea, I've only recently heard of the chasis dyno wondering how people liked them and also never heard of getting a "speed density" tune until the other day (apparently I'm falling out of the loop... I'm just wondering what the differences are and why they significantly more expensive than just a regular tune (cause I'm used to seeing $400-$500 for heads/cam tunes), and if this "speed density" tune can be performed on only the chassis dyno or both.

You can street tune anything just the same as you can tune it on a dyno. A dyno is great if all you are worried about is WOT, but tuning on the street and at the track is the only way to really optimize your tune.

Sorry to continue talking about ECS, but according to ECS's website, on the dynapack it's $450 for stock internals and $499 for cam only.
99 T/a...I think the reason the Speed Density tuning is more money is because it's much more involved to tune a car to run without a MAF sensor than it is if you kept the MAF sensor on the car.

Prices have gone up then, when I went before the dynapack it simply wasn't

The type of dyno has little to no bearing on the quality of the tune. The number itself dosent matter, its the increase in power and the ability to measure the a/f over rpm at a given throttle position. Once the a/f ratio is down you can adjust timing to get the most power before detonation. The variances in the total number dosent matter, as I said it is the change that you need to look at.

Yea, that's what I am just wondering about, is if there is a difference as to how good the tune is on each style of dyno, can one be more percise and yield higher gains than the other and if so which one is better? Or are they both the same and it is strictly just the individual doing the tuning that makes the difference in how much the gain is, and how well the ratio is maintained?

Josh beat me to it. If you gain 5hp and 10ft lbs of torque through a tune what's it matter which machine it's on? A gain is a gain. I'm not quite sure how one dyno is better than the other for tuning. Then again I don't know much about dynos.
Now, if you need dyno numbers to stroke your ego then go with whatever dyno yields higher numbers.

Numbers aside, you want a tune that is going to make the car behave the best. It's easy to throw a car on a dyno and shoot for a big number. But if the car runs like **** at anything except wide open throttle, was it worth it? To me, no. You want the best drivability IMO in a tune.

Yea, that's what I look for in a tune. Not worried about highest number, just smoothest most on point powerband, so that's what I've been asking about the two different dyno styles, is there anything more in-depth tuning that only a chassis dyno can provide or does it not matter which one is used cause you can do the exact same tuning methods on both?

The dyno itself is just a tool to allow the shop doing the tune to run your car @ WOT or hold it at various other RPMs - things that could not be legally accomplished on the street in most cases.
Best thing to do is choose a shop based on it's reputation, and not about what type of dyno they have.
