Big loss of power

Hi all,
I have a 2011 2.0 petrol ecoboost turbo estate with powershift.
I have a big loss of power, there are no warning lights on dash. I connect forscan and there are no codes logged anywhere. Everything is clear.
When driving normally it will drive OK, will change gears up and down ok, but soon as i want to out my foot down it doesn't want to know. It doesn't hold back, no misfire etc just doesnt do anything apart form take its time to get up to any speed.
Any hills and it slows it down, and i cant overtake.
Ive removed the rubber pipe that comes off of the turbo and goes down onto the metal pipe. The rubber hose has no splits in it.
Air filter is good, plugs are good, oil is good.
Ive tried disconnecting the battery and leaving it overnight but made no differnece.
Its doing my head in as I have nothing to go by, no codes nothing!!

Anyone had or heard of this problem before??

Sounds like a boost leak if there are no warning lights.

Live data boost pressure?

USB cable or bluetooth one? If its bluetooth check the torque app from the

phones playstore. Torque app maybe easier to check the boost it can give

you numbers or a gauge/graph.

So, I got home from work, thought I'd try forscan again and i find this code
"P132B Turbocharger/supercharger boost control A performance
Aditional fault sympton
-signal amplitude less than minimum"

I really hope that does not mean a knackered turbo... :(

When measuring the boost you need to be driving it, I don't like the Forscan

option of showing boost. The old F-Super and even the free torque app are

far better in that respect.

98.7 look s a bit like atmospheric pressure which will change depending on your altitutude

and the weather.

P132B old code that was the MK3 Diesel Mondeos PITA. Sticking turbo vanes or actuator

issues.

Variable vanes on that turbo? Vacuum operated or Electronic?
