2005 focus tdci intermittent low power

[flatlectric]

2005 focus 1.6 tdci intermittent low power. no fault codes just won't rev and has very low power. 

Turbo was changed with a CHRA core and an upgraded nozel ring as well as usual strainer and feed line. 

When cold the first couple of miles are slow then it wakes up and will run fine (mostly)

I replaced the MAF as i noticed that it did help with the reving issue when parked but when the new one is on it was the same

I have a feeling it is something else. I've tried nothing and i'm out of ideas.

Any help would be great as i'd hate to send it to the breakers as it would be a great cheap car for someone

Have you tried Forscan or just a generic fault reader?

Who done the turbo? Was it a.decent company or did you buy the bits off eBay? We're the vnt vanes calibrated again before turbo installation?

I have tried Torque, a handheld and even a solus and there are no codes at all

So nothing Ford specific?  I really would try Forscan personally.

i bought a turbo core off eBay and it came with a balance report .

I don't remember there being any adjustment on the veins.

I did download the trial version but it wouldn't connect so i binned it. didn't feel like paying for the full version if the trial won't even see that car
