Default GTB1765VK slow spooling

Hi guys.. I have bought Ibiza 6L FR, 96kw, BLT... Turbo is swapped for GTB1756VK vacuum converted... Turbo is spooling to late... No leaks on intake hoses... Vnt regulation is working good... Vacuum hoses good... Actuator moves freely, on idle resting on stop screw.. stop screw set with vcds basic setting group 011... The highest pressure I can achieve is 1044mbar... Do 75mbar difference between 100% and 0% duty on 1400rpm... No matter which way I move stop screw ... intried to loosen actuator rod lenght but no difference, just overbooating in higher rpm.. I even tried to plug vacuum hose directly to actuator, and still spooling very slowly.

Hi Mr.freezer,


Did you fit the BT in the car? If so have you mapped it yet?


If that the case you may need to get a re-map first and than see from there

If the guide/alignment pins become loose, your vane assembly becomes toast pretty fast. Inside of 1-2 weeks you'll lose all ability to build more than ~5 lbs of boost. Take the turbo off and open it up. If you need a new one, this is a trusted source and less expensive than eBay for shipping to the US. The part number is listed if you want to shop around.

I bet that one pin is loose and your vane gap is 4 mm or more.
