Unhappy D16Y6 into 1992 eg4 civic

I have an eg4 1992 civic,
I have put a d16y6 (head code p2j, intake code p2k) into the rig, with a p08 ecu. I have a stock jdm d15b obd1 distributor. Stock transmission,
The swap was all fairly straight forward.. most of everything was fine, worked sweet, timing dialed in no hard start no driving issues all was well.

I am however experiencing a couple minor issues.

Idling (after an IACV reset procedure) is low and lumpy and intermittently will search (jumps up to approx 1.5 holds for couple seconds then drops back down).
I have replaced intake gasket and i'm pretty sure there are no leaks- stalling the engine with my hand over the TB it has awesome vacuum however there is a little whistle coming from the PCV valve (have replaced) pinching the hose though will make it hold vacuum for ages.

Vtec, Now when i first start the car and drive for a little bit and then hit vtec the first time it will hit ~4800rpm really nicely and rev throughout to 7200rpm and works how it should.. Then if i hit vtec again straight after it lacks power and falls over almost feeling lean. The cams do change over (audibly) however the power is lacking.
if i park up (20~30mins not allowing it to fully cool down) it still has this issue. It has to get properly cold before it works well again (for the 1st vtec)..
