I've been doing some research and found that dyno dynamics reads approx 10-15% lower than dyno jet. I will be getting it on a dyno jet next week to see what the differences are. I'll be sure to get a baseline run in too.

Thats not correct.
Same type of dyno will get you different numbers with the same car.
It depends how the dyno is calibrated. You cannot make any comparison unless you are using the same exact dyno, same weather conditions.

I know they won't give the same exact numbers but they will pretty much be in the same ballpark. Just asked for some approx numbers, typical numbers, wasn't looking for anything exact. I know weather plays a factor that's why I stated what the temp was. I had no clue everyone here would get so technical and try to prove someone wrong every chance they got lol.

I have seen dyno jet with 50 whp difference in reading numbers.
The only way to for a dyno to graph to be significant is when done same condition (preferably same day) on the same car with baseline dyno numbers.
There is not other way.

I had my car do 25 whp more in California than vegas. Same car, same mods, very close temp ( ~80) , different dyno ( both dynojet)

Why did you dyno your car twice with the same mods on the same type of dyno in the same weather lol?

I have used dyno dynamics rollers many times in the past, and always found them to be extremely accurate. But i guess it comes down to how regularly it gets calibrated.

Depending on where you dynoed in Calif. elevation could be part of it, Las Vegas is 2,200 ft.

Agree 100% elevation is another factor that can also make dyno figures vary.
