Car accelerates well until just over 3000 rpm then goes flat and get lots of grey smoke get code 00575 map sensor (this type inside ecu ) any usual suspect to check? or any other areas

Cheers Jason will check through that list engines done 185,000 oil is checked regularly since I've had it  and toped up when needed was a little hesitant  on full throttle when I got the car but got worse.

Actuator works 

Vacuum pipes are original braided will change them all as most are fraying badly 

Turbo pipes are dripping with oil could be down to long term neglected cleaning but will check the turbo for wear.

 

Can you confirm vacuum hose sizes is it 3.5mm 4mm and 5mm ID ?

Hi all classic signs of a split boost hose which allows to much pressure to be lost and fouls the MAP readings

Cheers guys map is connected but have the type that's inside the ECU I haven't had a chance to look at much yet as my wife's daily drive and don't have a garage so work is dominated by weather I will get back to you all as I work through this and update.

Can you confirm the smaller vac line sizes please as most of the cotton braiding has rotted off and may be causing the lines to collapse.
