1. Personally my car likes an A/F of around 10.9
2. I haven't messed with my timing. Its base setting is 23* on the tt speed density chip
3. Start low with the boost and gradually bring it up just like any other kind of tuning. You shouldn't run out of fuel with the bigger lines and double pumper.
4. My injector pw was right at 17.1 to 17.3 at 24# of boost. My injector duty cycle was 75% with stock lines and double pumper and a 6765. I haven't tested my car since i went to bigger fuel lines; still breaking in the trans.

I have been running mine in the 10.8 to 11.0 AFR range with 22 degrees of timing at 28psi boost and have seen ZERO knock on any of the fast data logs. See sig for mods.
