Default Peak torque tuning

What are you guys doing to timing and fuel @ peak torque?

i take it easy on it, both fuel and timing wise. look at the stock z06 table, you'll see a little 'safety bump' in timing tables. fueling isn't as touchy, but as timing changes, AFR will too, so you might wanna adjust that particular stop. you just don't want things to blow up, as peak torque means you're at peak cylinder pressures.

I was under the impression that if your A/F ratio changed as you changed timing, then you don't have your fueling part done right?

Timing shouldn't change A/F ratio that much. From the dyno testing I've done, the change is negligable.

Richer AFR and lower advance from base rpm (stall point or launch rpm after traction hits) to peak torque then smoothly transition to leaner AFR and more advance as you approach peak hp. Thats what I have always stuck with and seems to work.
