Modded FICM rough idle

[qcfarmer]

I just replaced my ficm with a 58v unit and now I find it idles rough and low (around 550 rpm). It also seems to be more sluggish than it was before. Any thoughts on this? Rhanks

you might have some injector stiction causing the injectors to not be able to respond fast enough...

It ran fine with the stock ficm I was running. I borrowed a stock one while I was waiting for my modded one and I just swapped over to the modded one and find its running rough and low power.
