Hey Steveo thanks for the reply. Definitely looking forward to getting to the bottom of this as I am so close to having this car perfect!

- I hear rattling (knock) at WOT. This is confirmed by my ever increasing knock count on Tunerpro. The engine has about 30 miles on it, its brand new. I have Z06 Injectors now so plenty of injector and pump. Logically I agree, plenty of fuel, timing "seems" low, car should drive well, yet it rattles even jumping into it at 1500 RPMS. I don't feel like anything is "broken" at this point, car drives well locally and under light and part throttle.

- My wideband is showing an AFR when I go WOT of about 11.3

- Attached is a photo of my spark plugs. I decided to include a copy of my tune as well in case anyone whats to critique it (be nice please)

- I agree again that I may need a less sensitive knock sensor but I can also audibly hear the rattling, this makes me nervous.

1. The wideband is reading 11.3 at WOT, in accordance where I decided to set it to start it.

2. I'm not sure how to answer your second question. My aldl data says 18*, I thought I could take it at its word??? I will attach a log as well, but its not a very good log. I didn't do much driving before laying into it although it was up to operating temperature
