- Torsion at 0.5
- New timing belt water pump/cam/followers
- no black smoke or and strange behavior
- Had hesitation and then boost spike at 1800rpm before
- limited VNT to 160mbar difference and have no spike now
- Boost spec vs actual is low until around 1800rpm and then matches again.
VCDS logging confirms low boost. Until 1800+ rpm. VNT actuator holds vacuum and starts moving around -3 and hits the stop at -17
