the gas feel hard when i try to speed, and also i only get around 350miles for full tank, before i use to get between 500 and 550 miles per full tank.

93k miles
2006

could UN-tracked front wheals cause this amount of fuel lose.

More info, I take it this is a derv? A quick google says all the injector values are in tolerance, so no problems there.

Not sure what you mean when you say the gas feels hard?

the acceleration is tight. in order for me to gain speed i have to put my foot all the way down, and i think that is why its drinking fuel heavily.

Does the turbo sound/feel alright? Log block 115 to check if your boost is getting near target. log a block with mass air flow aswell, to get a rough idea of the power it's putting out. For example, my car will take 180g/s on a 3rd gear pull to the redline, which means it's roughly putting out 225ps, which is what it's supposed to.

I would check if the back brakes are seized, fairly common issue especially if they are not used very hard.

THE TURBO wisles, but it was like this before and the car was fine on fuel. Is it easy to clean the turbo as the injections are working fine I will take to my friend who has the vcds to check the mesureblocks 115 on the engine 3. is it easy to clean the engine

They are known to seize and stop the wheel from spining freely resulting in poor economy and a reduction in performance. The proper way of checking them is too jack the car up and see if you can spin the wheel, an easier method is too take the car for a drive and see if any of the brakes are hotter than the others.

Is this a 1.9TDi?

Log block 3 for MAF I think. You'll need a passenger to watch the value as you stamp on the throttle in 3rd/4th. It should hit 800~ odd and hold there. If it doesn't new MAF time.

If you see crazy low value like 200 spiking, just unplug the MAF until you get a new one. It should default to 350 and hold there so it will be a bit better to drive.

Lots of info online suggests ignoring the injector quantities above as the ECU has no way of measuring the actual delivered quantities.
