I have a 06 z and have an appontment at 1030 this morning to get it dynoed. Now here is my question, I only have like 600 miles on it is that to soon to push it on the dyno? I cant decide...

 

It'd be better to wait probably but I don't think you'll be running it hard enough to really hurt it a lot.

 

It will only be three baseline pulls no tuning or anything...

 

it will be fine

 

Once you've run it for a couple thousand miles, it will be broken in and loosen up some and you'll probably see more power out of it than what you'll get now.

 

Technically you shouldn't because your not out of the break-in period yet.

But its your car, so you can also do what you want.

 

That is generally the case. I took my Z to the drags when it had 500 miles on it. I have done this several times with cars and never had an engine problem.
They seem to run stronger if you whip them a bit in the beginning. That's just my experience, but putting 1000 miles on it is the safest way to go.
