Lean on throttle application then super rich on decel.
 

Any ideas to why this is. Please see pic. (Haltech E8)

The lean area on steady throttle is just the wideband 02 closed loop correction.

Also what do you guys use for the base injection angle split map for the secondary staged injectors, extra load bar for staged injection and end of sequential injection angle map. I was just using what the base map that is supplied from haltech.

If you're lean on sudden throttle movements you need to revise the throttle pump settings, which i must admit is pretty different from how it used to be with the E6's, but when done right can work well. You just need to get the theory down on how to set it up. There's some information you can read on it here:

E8/E11 Throttle Pump Setup

But what does the throttle pump have to do with letting go of the throttle. i thought it was just for throttle tip in.

Thanks,
