I have a 2.8L turbo diesel hilux with a DTS turbo and have put a boost contoller on it and when i screw it the way it said to increase boost it decreases boost any ideas?
even if he did get it in upside down, backwoulds and inside out ! , it should still give stock boost or max possible. unless he ripped the spring out of the diaphram then there is no way it should go lower than stock pressure.
if its backwards alot of then have a vent to release the pressure once its closed off. The boost pressure will just escape through the vent and and never acutate the valve to let it through to the wastegate.
IT IS NOT BACKWARDS!! you have to screw it clockwise untill it stops and that is the factory setting and anti-clockwise to gain more boost but in this case it decreases boost. And i never got it off E-bay it comes from Rocket Industries. I will talk to a turbo specialist.
it is a GFB boost controller. I have turbo outlet>boost controller > Tpiece>boost gauge> waste gate. I have the gauge after the contoller just in case it may show a different reading if i have it before. I took the car for a drive before fitting the controller the boost was on 8 went 2 srews out which it said to do never made a difference which it said to go another 2 done that and the boost dropped 1psi went another 2 and it was down to 5psi got me stuffed? Any one in here fitted a boost controller to a diesel?
your problem is simply boost gauge is plumped into the wrong place. it needs to be on the turbo outlet side of the controller.
infact the gauge shouldn't even be on the turbo at all. best place for the boost gauge is the inlet manifold otherwise boost readings will be incorrect.
