Negative on that... DynaPacks read lower than mustang dyno's.. not by much.. but they do. My best friend/neighbor owns a dynaPack. I run the machine..most of the time, we were both trained on it, by Dynapack themselves (they fly out and train you for 2 days). We have done back to back testing with our dyno and a local mustang and a local DynoJet.
DynaPack is consistent every time, and read lower, mustang read a tad higher and was pretty consistant.. DynoJet was all over the place.. plus we can fudge those #'s pretty easily to get higher hp ratings. Cant fool a DynaPack since your hubs are directly connected to the machine itself and it uses fluid dynamics to measure torque then calculates HP.

I wish it were true though, but its not. Sorry for the threadjacking!
I agree with the other posters though, that you need to get the car to the track. Dynos are only tuning tools, the real measurement is on a timeslip. If the car is running good i the 1320 then it is fine, take it somewhere else and get dynoed for peice of mind.

do you have a graph? i agree that dynos are tuning tools, nothing more.
i'd guess my car to come up ~310 rwhp unlocked on a dynojet, but that means nothing as the car consistently runs 12.2s @ 108/9 dragging 3,500 lbs.
as long as the a/f is ok, take it to the track and see what you come up with before you get too worried.

the LS6 cam is 204/214 550"/549" I made 360rwhp untuned throught stock heads and bolt ons on a dynojet in the hot sun on a trailer in the middle of a parking lot in June. Granted I Also had the 1.8 rockers which make my like 583"/579" That does seem low to me Althought the lift on that cam is pretty small

bottom line is that a roller dyno reads at the wheels and a dynapack reads at the axels. A roller dyno will never read as high as a dynapack or other similar dynos.
If you dont beleive me, here's a website with the actual math to prove it.
