From what I have read A/F is by far the biggest gain on these cars stock. Their A/F ratio is very conservative from the factory. Getting the car too lean is definately a concern, to be on the safe side I would tune the car to around 12.8:1. For reference my car bone stock with 3K miles had an A/F ratio of 11.5:1...Tuning my car to 12.8 or so would probably net about 10 rwhp. Most of what I have read (but not all) says that the stock settings for WOT timing (around 24 deg) is a nice safe setting.ROSSO Z said:To what specific item changed during the "tune" do you attribute the most HP gain? If it is changing the air/fuel ratios, does this run the risk of running too lean and too hot?
I am ignorant on this subject. I was going to get a tune this summer and want to know the risks/rewards.
Thanks,

What is the torque management? How does it work?niphilli said:From what I have read A/F is by far the biggest gain on these cars stock. Their A/F ratio is very conservative from the factory.

For a tune on a stock car or bolt on car I would suggest leaving the timing alone, tuning the A/F to around 12.8:1, installing a colder Tstat and programming to its corresponding fan on/off points, remove torque management (if you want), and decrease COT protection by a little (again only if you want).
What tune program and who did the tune Norm?PerforminNorman said:We tried for hours on my 02 and only got 1 horse out of it.
Torque management is when the computer recognises that you are getting rough with the car when shifting and pulls timing. Zs dont have a big problem with this like the new C6s do, but they still do have TM. Basically it pulls timing to limit power so you dont break any of the drivetrain components when you are driving "spiritedly".droid said:What is the torque management? How does it work?
