and little did i know but over time the switch i used (little toggle switch) was breaking down with the load (as i found out from dynodemon the walbro draws quite a large current from the battery)
therefore the switch being underated was causing resistance (the switch was actually getting warm under load) and hence this resistance was causing the fuel pump to actually slow down so when the car was boosting over a certain rpm and the ecu was calling for more fuel press the pump was failing causing the car to lean off at high rpm( a dangerous situation) as it could have popped a piston or arod
this was confirmed on the dyno by the fact that the trace was tailing off at 5ooorpm when it should have been climbing up the bhp scale! the ecu was actually recogonising that the fuel was weak and was cutting the boost down to prevent engine damage(safe mode) therefore casey and others recommended i remove said switch and rewire the pump properly! which i did today and hey presto it goes like fek again! 
i would never have thought such a simple switch could cause so much agro!
but all is well again now and a lesson learned! thankgod for dynoday!

A: you have been reading up on threads about what someone has done to there car and you thought
i can do that?B: you fitted a dodgy switch, wrongly
why dont you spend some of that cash that you hide under your bed and get someone who knows what there doing to work on your car
