Because DG changes the CF by a LARGE percentage regularly. Their drag car is at 1.2, some evos are at .995 some are at 1.0 and now 1.15. Using a CF is FINE as long as you stick with ONE and either do NOT change it or make sure to show it on every dyno graph you print/publish.

Most people don't understand that a dyno dynamics reads so low, so I can understand why they would want to use a higher factor because all the nubs don't understand how much power you are making and then they think another shop is magically better because their dyno reads higher. The forum is a means to get clients as well, so trying to make them read like other dynos do so people who aren't as educated think the shop knows what they are doing is a decent reason to change it. But like you said, just keep it constant i guess.
Personally I agree, just stay with a 1.0 which is what they seem to be doing, but as long as you can see what they are running, it's all good.
Scheides we both know how dd's read, we both dyno on them.

1% of the cars we ever used a 1.2CF on are:
Our drag car- proved to trap the whp we showed- (164mph)
TeeJay's Evo X- 38psi on VP Import w/ a 3586- (How could that not make 600+ on a dynojet?)
One other clients 35r/aem- 465whp @ 27psi/93 Octane
This 1.15 car was used via customer request.
All other cars will range from .995-1.0 depending on the weather as we run a weather station. It will have a small range. To be honest, a .005 difference will increase or decrease power by 2 or 3 hp at most. If you look through the last few tunes I have posted, they all range between .996-.998.
All tunes from now on will not have an option to change correction factor. It is nice to be able to honestly give the customer the option but has proven to deter these threads just too often.

I tuned this car so I feel as though I need to chime in. Charlie was running late and Pete called me and asked me if I had time to tune a car for him. Pete's shop is one town over from mine, we both specialize in Evo's, and I have not yet had any reason not to be friendly towards him. I did not set the dyno up but as far as I know the numbers are legit. I would be very upset to find out otherwise.
The correction factor is stated clearly in the first post. I usually tune cars at a 1.15 CF on a Dyno Dynamics because my customers rarely come to me with Dyno Dynamics whp goals in their head. The numbers they have read about and are shooting for are usually Dynojet numbers. I tell them a correction factor was used, explain what it does and write it on the dyno sheet.
I don't want to have to drive all the way to Queens just so I can get on a Dynojet when I can get very similar numbers with a 1.15 CF.
My apologies to the OP for continuing off topic with this post.
To the post below. I like TSA, it's just a far drive for me however in light of the stuff currently going on with DG I might have to find a new place until the dust settles.

Incredible. The correction factor is stated clearly in the first post. To those who have complained. When you get
your car dyno'd don't use a correction factor but please don't tell other people what to do.
I would take serious issue with a shop using a correction factor and then concealing that fact and I know that there
are shops that do it.
But in this case a correction factor of 1.15 was used so that the customer can more easily compare the numbers he
made to Dynojet numbers.
I tune cars at a 1.15 CF on a Dyno Dynamics unless the customer requests otherwise and this is why.
My customers usually don't come to me with Dyno Dynamics whp goals in their head. The numbers they have read
about and are shooting for are usually Dynojet numbers. The dyno sheet is for the customer.
I tell them a correction factor was used, explain what it does and write it on the dyno sheet.
I'm not driving all the way to Queens just so I can get on a Dynojet when I can get very similar numbers with a 1.15 CF.

SUMMARY: If the CF factor is clearly stated then do the math in your head and try your very best to keep your contempt
for CF changers to yourself.

I'm sorry that people haven't been honest with you Adam.
You can always contact "Manny".... His awd dynojet is located in Farmingdale 3-4 blocks from Top Level Performance...
