    Lean when revving. Slight idle surge. Please help

    09 challenger 6.1 with an Eforce, FIC 1000cc injectors, 295 fuel pump. Internals of the engine are unknown, im assuming stock. Cannot get the idle smooth, looks like spark is up and down at idle, after much research, ive adjusted every table to no avail.

    When i rev it in neutral, it goes way lean. Is this a VE problem, as i have not finished the VE tuning yet.

    These issues happened after switching to 1000cc injectors and fuel pump.
