Default fiesta turbo idle/running problem

i'v got a problem with my fiesta turbo,just had new engine built an fitted when i start it hot or cold it idles around 1100rpm then drops to around 600rpm then hunts about an wants to cut out if i give it a blip of the thottle its clears an wont do it again.
the other problem im having is when im in traffic or approaching lights when i slow down the revs drop with the speed of the car as normal but when i put the clutch down it will rev itself to 1900rpm for around 6seconds then idle at 1100rpm it will constantly do this even if your crawing in traffic in 1st gear.
lastly the other problem is that it wont rev past 5000rpm
i'v done the running in mile's an had the fueling donan tried 4 idle valves to try cure the idle problem.
the engine is a 1600cvh,t3,beiges,285t2 cam,195 chip
thanks to any1 who can help or give me some advise.
