Which wideband are you using to gather AFR data?
He's not using a wideband. To my knowledge he's yet to even pull his plugs and check colour.

@JmcEx2fifty You're running a 500 engine on pods and an open exhaust. If you're going to tune by throwing random parts at it instead of actual data, just try shims under the needle like people normally do it'll probably make a big difference and can by fine tuned way easier. Different needles may help but properly adjusting main jet size and needle height is going to make a big difference for basically no money.
