Dyno Results WCCH Heads Stock Cam
 

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 :eek: 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.

:cheers:

Congrats Tank!

Great results Frank, most important thing is that she is solid.
:thumbs::cheers:

Not bad man, and my car ran very lean prior to my tune when I did basically same mods (excepted added ported intake also). Which is why tuner and installer specifically told me never to get on it until we tune it

:thumbs:

:rock:

Yea I've been driving on it for 2 weeks without the tune , not daily just here and there but never got on it hard or got even close to redline, now I am glad I didn't ! :eek:

Thanks Bob. Too bad this weather blows!!! 40 and Rain!! Gotta love Chit-town/burbs weather in may.:ack:

Basically how long I waited as well and drove it. But now you can go enjoy it when it dries up for you

:iagree: :cool: :thumbs:

Now you can REALLY enjoy your car buddy without worrying about a thing! :cheers:

:iagree: and for a long time to come, and that's huge.

Frank....honestly....just how stock does the car drive? I mean overall. Great numbers and exact build I want to do but don't want to sacrifice any sort of drivability and comfort.

:rock: Yeap it is nice to have this done and pick up some extra HP,

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. :crazy: it doesn't do it every time though. :crazy: so we'll see.

If I didn't tell you it had a tune and let you drive it, other than it "feeling " faster and better throttle response you would not know its tuned. To someone who has never driven a Z before, they would never know its tuned. It behaves identical to stock. My car (even before the tune) has always idle hunted just a tad, it still does that, but from what I;ve told a lot of LS7's do it, its just nature of the beast.

:smash: That is key.

Now you know you have a good tune in it too, i.e. you trust the tune.

It really is a good feeling, getting your car back and knowing that it is as solid as any LS1, LS2 or LS3 out there, and that even out of warranty, you are now no more at risk for catastrophe than is anyone else with one of those cars.

Frank , hard to read the A/F . Could you read off the values at 500 rpm intervals..Thanks

Did you try clicking on the graph? It will enlarge then you can see it better. I'll repost larger if needed, that will be quicker than me typing it out :thumbs:

Congrats frank. Im confused though. Did you have a bad tune before? Were the baseline numbers 100% stock?

Those baseline numbers are with the mods and no tune. :thumbs:

Nice pickup then. Were the baseline and the tune done on the same day?

Yeap this morning actually. We did 4 pulls, 1 base line.. 1 with tune, then let it cool down for a bit , 3rd pull with tune, then the 4th pull right after the 3rd 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.
