The numbers are lower than a stock Z but many things can contribute to both low or over zealous dyno numbers such as the type of dyno used, out of calibration etc. I wouldn't necessarily be too concerned, you could always go to the track to get a trap speed or go to a different dyno just for reference but I'm assuming your low numbers are due to the dyno in some way shape or form.

My car was dynoed/tuned multiple times @ Slowhawk Performance in MA, known to have one of the stingiest - but truest - dynos around. Mine made 352whp stock, 363 after intake/tune, & 384 after headers/ported TB/retune.

I dunno something is probably wrong/off/not calibrated accurately on his dyno if your car is running correctly even on a mustang dyno (which, IMO is the machine to use b/c the dynojets I've used & seen #'s from are usually WAY over zealous/unrealistic) - why do I say this?

At that RPM, the power should still be rising.

It's a 04z. What makes me mad is the owner from jtm said everything looked gd... I sent my pcm to doug from ecs then when I Reinstalled the pcm took it for a ride it felt lazy down low not up top weird? Then took it to jtm he said it looked alittle rich down stairs... I called doug and told him now he is calling John from jtm also these guys are buddy's so I hope it turns out ok? What scares me is John is telling me the dyno sheet looks gd.... this is on a dynometer

I am waiting to hear back from John, but that is a Mustang dyno. Also what was the temp when it was dyno'd? timing could have been being pulled from high IAT's. It's been very hot here, that's for sure.
Just speculation since I have not seen the log, but if John said it was on then personally I trust him, what is his benefit in lying? I'll get back to you when I hear from him.

I don't understand what you are saying? It's a Mustang dyno, they read low, if the A/F and timing are in place then there's not much more to expect for a car with a cold air intake IMHO.
How do you know everything is not OK? "A little rich down low" takes away next to nothing on HP and wouldn't effect the upper end regardless. I intentionally make most cars a little rich down low, I have found it decreases detonation up top. Not a pig rich mind you, but if it was then he would not have told you it was OK right?
As I said though, you are welcome to come here and I'll data log it for N/C, can't beat that for just a mail order tune that was confirmed "good" by another shop. All shops are in business to make money, if there were any corrections to be made worth making, they would have justifiably taken your money to do so.

Can't go by that, the car is a manual, way to many variables to say the car should run "X" MPH. I couldn't tell you how many times I jumped in the seat of an auto and put 5 MPH on the owner, let alone manuals. Simply because I have thousands of passes down the drag strip, it's just like bowling, there's a knack to it. Not saying this individual cannot drive nor do I know his track experience, I'm sure he is awesome, but track experience makes a big difference on MPH just as much as ET.
