Er34 Power Fc Idle Issue

[Godzilla34]

Hi guys, I have just recently had a power fc and tune done on my r34 gtt the following mods are:

-FMIC

-FULL EXHAUST

-POWER FC

-BOV -PLUMBBACK

-Walbro Fuel Pump

So whilst driving and boosting all is ok, whilst coming to a stop and putting into reverse or just idling the revs of the car go from 900-1200 than back down than back up again, it has only happened since the tune has been done so obviously something to do that. The fuel pump and fuel filter was replaced, new penrite fully synthetic oil + filter , major service has been completed, aluminium radiator, water pump. So if anyone can tell me their suggestions that would be great thanks.

Is probably bouncing between cells at idle. Did it get the correct idle learn procedure when installed?

To be honest with you I am not to sure, i took it to a reputable tuner which has a good rep of installing power fc, it only does it for a few seconds and than it clears up and is all good again, but i never had this problem with the factory ecu i am not sure if it is a problem just thought it do a quick report and see what people had to say.

Possibly worth checking the idle with the TPS disconnected in case PFC setting is too far away from where the idle screw is set.
