First time on dyno with wierd results. Please explain!
The RPM pickup is probably set for the wrong number of cylinders thus you get a higher RPM reading. Since HP is basically TQ x RPM, you're also getting a higher HP reading than you should.

305.3 HP (284.4 with Correction Factor) @ 6189 RPM /91.6 MPH
323.8 TQ (301.6 with Correction Factor) @ 3776 RPM /63.6 MPH
Anyone ever heard of Nistune? He's saying I could probably net another 12-15 HP with a reflash.

Keep us posted on what happened when a knowledgeable operator is running the dyno. Have you had any tuning done to your Z?
Mustang dynos can have crazy results depending on the info the operator inputs. They can change the vehicle "weight" for example and throw everything off. Most operators dont input everything to give you a solid number so I avoid those personally.
On a Dyno Dynamics they can mess with correction factors and throw everything off. For example 1.00 correction is true number. 1.10 is adding 10% which many shops do to try to replicate a DJ. Some even add 20%, its BS.
On a Dynojet which seems to be "industry standard" not much in the way of altering other than a handful of "corrections" and some smoothing, which dont make a big difference.
The first operator should have made sure he was pulling the rpm signal correctly, and then made sure the signal on the dyno screen was matching your tach. Lazy tech man.
If you went back a 2nd time and they told you 3XXwhp, they are still doing it wrong, dont go back.

See post 28... It is a drive up type. I'm never dealing with this place again. They obviously don't know Z's or their dyno. What a waste of time and money. I'm gonna head over to RT Tuning or JDS Motoring when I am ready to have my serious work done. I'm not even letting this place do my coilovers.

And i'm with you.. dont go back to that place for your Z...
That video and shop is a joke. That guy sounds like the biggest douche ever. You're probably around 265whp on RT's DJ. My car is there right now.
