Yeap this morning actually. We did 3 pulls, 1 base line.. 1 with tune, then let it cool down for a bit , 2nd pull with tune, then the 3rd pull right after the 2nd almost to see how it would pull with it hotter to see if it was pulling any timing etc.
It was pretty cool actually so the low humidity, and 69 degree temp I am sure helped a bit.

Either way good stuff and im sure you are happy to have the head work done.

unfortunately my next adventure now will be possibly trackling the Tranny...somehow my Syncrhos in R I think are f'd...every now and then when I go into R , it makes loud noise like it does not want to engage and then it will pop into R. All forward gears are fine and have no issues. 
it doesn't do it every time though. so we'll see.
it doesn't do it every time though. so we'll see.OUCH, my 06 Z had the EXACT problem Frank, and it was fixed under warranty by Kevin P, 1.5 years ago under warranty.
He told me the reverse gear had to be replaced which was done and problem was then fixed (under warranty). He told me it was a very expensive job as the whole tranny had to come out and get taken apart, etc. The good news is that you can drive the car like this for awhile with only this intermittent inconvenience, and don't have to rush to get it fixed.
Good luck with you new build buddy.

I'll just keep fingers crossed I can at least make it through til Winter. No more funds available at this point for the car.

Oh Boy, here we go, Keith, you would have to bring this up again, huh? 
I have been bustin Tank's ***** on the no cam issue for months now, and here you go having to bring it up again, just to keep the issue alive and well!
Sorry Tank, just couldn't help myself, b/c you know next season the Torquer 110 is going in!
Keith, is your new heads and cam BEAST done yet? Did you hit that magical 600rwhp?

Frank, you did this strictly for peace of mind or did your engine exhibit any signs of pending issues?

Thanks man 
I know I haven't heard the last of it
Peace of mind . Even if my guides ended up being in spec I still would have done it. I have no warranty and wanted to enjoy the car more. And someday I may even want to track it

Reason I ask is my car had been set to the same A/F ratio during dyno tuning.
Previous cars I owned (F.I.) had A/F ratio's around 11.5 -12.0. Going above these ratio's is considered un safe.
My concern for this car is at what level of A/F is it considered un safe?
Sound like 13:1 is ok..

Got the tune and 4 Dyno pulls done. I am working on getting file uploaded so you can see the actual chart, stay tuned but for now:
07 Z06 26k miles stock cam.
Mods
Halltech MF103
WCCH Stage II heads( ported)
Melrose 1 7/8 LT's with catted xpipe
160 Tstat
Tune was done by FLP Motorsports. Dan who tuned my C5 back in the day is somewhat of a conservative tuner. He told me bone stock Z's dyno on his dynojet average anywhere from 420RWHP-450RWHP
My baseline pull (with the above mods) was 459RWHP 437RWTQ
After tune with mods 474RWHP 452TQ (SAE corrected)
.
I will also say before the tune my car was actually running lean
so I had a lean code CEL, and of course the CEL was on for highflow cats
Overall I am happy with the car, it didn't get to 500RWHP, but the car drives perfect, and the tune did definitely wake the car up. I could not push it too hard on the way home as we are getting soaked with rain..hit a few dry spots and blipped the throttle and you can tell.
69F , 28%humidity
