I talked with Richard @ Dyno-Comp today. The car has been dynoed/tuned. The approximate numbers he gave me were 310-320 HP at the wheels. He said he talked with APS last night and they said that those numbers were right in the ball park considering I'm running the stock exhaust, stock cats, and 91 octane. The car is running about 7.5-8.0 pounds boost. I neglected to ask the torque number. I'm sure I'll get the full dyno sheet when I pick up the car on Saturday.
He said the number would go up about 40 HP if I add the APS exhaust and cat delete. I can't delete the cats due to Nevada emissions, so I guess high-flow cats would be my only option. He also said that he tunes the car for safety......no blown engines wanted. He tunes it to minimize any possible heat from the back pressure of the stock exhaust, expecially with the hot Vegas summer on the way.
The load bearing dyno they use usually gives them a baseline of about 210 HP for a stock Z, so these numbers may be bit low compared to other dynos.
I'll give a full review after I pick the car up.

That seems verrrrrry low. APS says 8psi is perfectly fine, so no worries about blowing an engine... Usually dynocomp tunes safe and good performance... weird... But ya I would get a custom exhaust and test pipes... i mean when do u have to go emissions again? And when u do.. just put ur stock cats on.

They test here every year. I really don't want to change out the cats and retune twice every 12 months....especially since there's no one in Las Vegas that can tune the unichip software.
Maybe Peter will respond regarding the power. Perhaps this is what to expect from this setup and 91 octane.

What? "Carb" is California only. It means: California Air Research Board.
In Nevada, the TT system is fine if I can pass the emission sniffer test.....that requires some sort of cat.

Did dyno comp actually tune the car or is this the out of the box tune? I am confused. You say dyno comp tuned the car for safety but the kit already comes tuned for safety.
Here is a quote from Peter on another forum stating that tuning is not required. http://g35driver.com/forums/showthre...5&page=2&pp=15

No further tuning is required unless significant changes are made to the engine's specifications such as low-comp pistons, high performance cam shafts etc. Then - and only then - is additional tuning required and it is our opinion that this tuning work should be performed by a highly experienced tuner on a load based dyno.

When you have the chance, please post the dynos. Curious about the torque and a/f ratios. The dyno that Richard uses will show lower numbers than a dynojet. I would trust his tune for the desert conditions. Most people that haven't lived in the desert have now real idea of the intense blast furnace that are our summers. thanks for the updates.

the question, though, is... why? I definitely would rather have the company that designed the kit in the first place to be tuning the kit (ie out of the box), versus someone that is just installing it - regardless of his level of expertise, he is still not the guy who designed/fabricated/R&D'd the kit...
If you are looking for safe - then you shouldn't mess with it in the first place... esp. if that's not the exact area where you live...

His numbers sound right.My TT dyno was 360/340 93octane map from GRD/Tuan.That was with H/F cats and stillen exhuast.I just had test pipes installed and I can tell you I gained 20hp or more haven't redynod yet.APS's TT kit according to there web site is 380ish with 9lbs of boost.H/F cats and exhaust will make a big differance with any turbo kit.Also my A/F 10.1 from 3k to red line.

That said Richard did emphasis that he was being very conservative with your car/engine because of the stock exhaust system being retained and the very high ambient temperatures (up to 115 F) and the fuel quality of the 91 octane fuel around your general region.
I believe that you will be very pleased with the entire turbo install when the car is delivered to you, by all means provide us with an udate when you've had a chance to drive and test your APS twin turbo Z car.
Thanks
