Ive been reading loads of info on the GTD forum, on how to tune the 1.6td's and 1.9td's!
They all seem to block off the standard blowoff valve by replacing the spring or using a 1/4" cut off bolt to hold the diaphram shut.!!
Surely this is unsafe?????????
i really dont know much bout Diesels and turbos, but surely whats stopping the engine from over-boosting!? Ive just screwed the adjusting screw on the top which bleeds the pressure off at 18psi.
What has every1 on here done to tune their TD's?
