Default ECUTEK, WALBRO pump and SARD 800cc's.. PROBLEM

Hi

I have just got my car tuned, runing a walbro 500hp type in-tank fuel pump, ecutek reflash, sard 800cc injectors, FP green which has been ported, ceramic coated, angle mounted etc
a heap of supporting mods, running 25 psi...

My tuner could not tune the injectors at idle, or hardly any load... The target parameters set in ecutek were stoich, although it was running excessivly lean with even 25% correction. He also did scale the injectors, but this wouldnt help things at all...
Once there was load, it seemed it started correcting itself properly (although out to some extent).
after 500rpm the walbro was running out afr's started to go lean

So im asking - to those ppl who run ecutek and big injectors, how is your idle? And how did u manage to controll it properly? Mt tuner is suggesting that the Walbro pump i have is not supplying enough fuel pressure to atomise the fuel with the big injectors...

opinions?

thanks
