ADU power failure

[juanra911]

Hi folks, I´ve got and RS2 with a SKN chip (381), another harder
wastegate spring and air filtering & GT3 wheels.
From few months ago the car has a big power failure. The engine hardly has enough power to climb the parking ramp .It has not power at few engine revolutions (up to 3000).
I have changed the Lambda & temp sensor (a little improvement in the car but not enough). Lately cleaned the MAF, less petrol “consumer” but problem not fixed.
The last solution is update to Samco Turbo Hose kit ( I just asked for one to S2cenmtral net) , thanks to “the Spanish” my master in these RS2 troubles .
Meanwhile the SAMCO hoses come, do you think there is another possibility for this engine failure?. The computer do not shows any problem.
Thx & rgds

"If you're in Spain, drive to Rafael and steal his one "
Yes we live in the same city, but he is on Holidays up to 27;-) and I need to travel with the car next 24:-)). In fact we are going to make together the Pression test:-)
The fuelpump was other possibility, I checked it it seems work correctly although when you press the acelerator harshly, the engine suddenly stop, has not response during a moment and suddenly begin to acelerate but not quickly.
If you want to have a nice response you have to acelerate softly. :-(
Thx

Boost leak - check the hose that goes to your throttle body - they split under the jubilee clip.

Aha. Boost leak it is. Could also be a leak before the turbo. Between the MAF and the turbo or the breathers!
