i am losing power between 3500 and 4000 rpm then the car is fine it feels as if not enough air/fuels is getting through

Could be anything. Let your OPC plug the diagnostics in. Is your car modded?

no the opc can not find out the cause with the car the air intake is were the fault is but the sensor is working

2 pipes from intercooler to turbos ,running North ,South , as it were, can come loose or 'tear' will only show up intermittently on diagnostic ,can also give yellow dash light' check engine' some exercise ...........worth a look

I once read of someones who's airbox baffles had collapsed causing the problems you mentioned.
