What injectors are they?

Are they new or used?

If used - Have you had them ultrasonically cleaned, and the spray pattern and flow rate checked.

If the spray pattern is bad, you will experience prolems with idling.

sorry totally disagree.

The Apexi is very good at controling idle.. I have Apexi PFC and 550s on my own car, it was a pig to get a nice idle on the previous ecu - Link, but the Apexi was no problem at all. It is one of the only (reasonable priced) ecus that alters the timing to keep the idle smooth.

It could be an injector fault or a mapping fault.
