The XIED will only work while in closed loop. But what most folks don't tell you is that the stock ECM Map is plenty rich in open loop (from ~3700 RPM to limit)
See attached AFR of factory map.

IMO, the XIED will be enough for air and slip-ons. Will XIED be the optimal setup "NO"; will they improve the lean condition "YES".
