This car is driving me insane. I have an XP cam with 130's, ported heads, headers, stock gen 3 supercharger with stock pulley, and stock L67 tb. I don't understand why I still have kr. I don't think my o2 sensor is hitting on the firewall, but maybe I need to hit the firewall some more to get more clearance. here are a couple scans and my current tune. My transmission dipstick is flexible braided stainless steel and runs up along one side of my headers and does rub, but I'm not sure if that would cause anything.
