Maybe not exactly the right spot for this but anyways. Afrs are sitting around 11.3-11.5 at wot and timing is [email protected] peaking at [email protected] which is limiter. Motor is a z6 with y7 cam, 5431e on 9psi, 70mm throttle body and edlebrock intake. This is about 5 degrees less than my full z6 with rocket regrind and 16g which burned down a piston. Anyways on to the pics. I want to add that I am not seeing a color change in the ground strap but I dont think more timing is the way to go here, do I need to install a new set of plugs? These ones have about 1200 miles on them.
